How to Use WAU Discount Codes: A Complete Buying Guide

Using a WAU code is quick, but a few details decide whether the order goes smoothly: the discount field, the euro total, your bank's approval and the delivery window on international orders.

This guide walks through each stage in order, from checkout and common errors to reading product pages, currency, payment methods, sets and spare parts, free shipping, delivery times, returns, damaged items, device safety and a simple routine, with short tables at each step.

Every fact comes from WAU's own policy and product pages and from our live cart test this month. The current code is shown on the cards on our store page, and we update the guide whenever the shop changes its rules.

Learning how to use WAU discount codes takes a few minutes, and the details around the code matter as much as the code itself. This guide covers checkout, fixing errors, reading product pages, euro payments, sets and spare parts, shipping, delivery, returns, damaged items and safe device use.

How to Use WAU Discount Codes at Checkout?

The code itself takes seconds once the cart is ready. It is listed for all customers and applied in the discount field before payment. The points below explain what this means for your order.

Where does the code go?

Add your device, skincare or set to the cart, open checkout and look for the discount code field beside the order summary. Paste the current code there, press apply and wait for the total to refresh.

What should the total show?

A separate discount line should appear under the subtotal, and the order total should fall by the listed percentage. In our test on 18 October the MIGA irrigator dropped from €108.95 to €98.06.

When should you enter card details?

Only after the discount line is visible. If the total stays the same, remove spaces around the code, apply it again and then pay.

1. Copy the code from our card.
2. Open checkout on wauglobal.com.
3. Apply the code before paying.

Is the code typed correctly?

Copy it from our card instead of typing it, and remove any space before or after. Discount codes on Shopify stores are read exactly as entered, so a stray character blocks them.

Did the cart change after applying?

Adding or removing a product can recalculate the discount. If the discount line disappears after an edit, apply the code once more on the final cart before you enter payment details.

Who can help if it still fails?

WAU answers questions at [email protected] and through the contact form, so send the code, your cart items and a screenshot of the message.

1. Paste the code again.
2. Reapply after any cart change.
3. Email support with a screenshot.

How to Use WAU Discount Codes When Reading Product Pages?

Knowing who the code is for and how WAU lists its products prevents most mistakes before the cart is even built. Here is what the official pages say.

Is it for new and returning customers?

Yes. The current code is listed for all customers, with no first-order limit in our listing. It started on 2 October 2026 and shows no end date at the time of writing.

Which products does it cover?

In our cart tests it applied to a device and to a reduced set. Single items, sets, cosmetics and accessories share one checkout, so the discount works on the order total.

Can the terms change?

Affiliate offers can be updated by the brand at any time, so look at our card on the day you order and use the code shown there.

• Check our card on order day.
• Apply the code to the full cart.
• Read the total before paying.

Why are some titles in Russian?

Many sets and supplements carry Russian names and descriptions. Browser translation helps, and the English device names, such as MIRA or YUKI, stay the same across languages.

What do the two prices mean?

A crossed-out price is the brand's reference price, and the lower figure is the current price. The code then applies to the current price, as our cart tests showed.

How do you confirm the right item?

Check the model name, version number and included accessories in the description, then compare them with the cart line before paying.

1. Translate the page if needed.
2. Confirm the model and version.
3. Check the cart line before checkout.

Which Currency and Payment Methods Apply?

Checkout runs in euros, and the choice between a card and a wallet affects speed and how refunds return to you. The details below help you decide quickly.

What does your card see?

Your bank converts the euro total into your card currency at its own rate. Some cards add a foreign transaction fee, so check your card terms if you buy often from abroad.

How do you estimate the local price?

Use your banking app or a currency converter on the final euro total after the discount. Converting before the code is applied overstates what you actually pay for the order.

Can the amount on your statement differ?

Yes, slightly. Exchange rates move daily, and refunds are converted again, so a returned item can come back a little above or below the original amount.

• Read totals in euros first.
• Convert the final total only.
• Check your card's foreign fee.

Which cards are accepted?

The store displays Visa, Mastercard, American Express and UnionPay. Your bank may run a security check on an overseas euro charge, so keep your banking app close.

Which wallets are available?

PayPal, Apple Pay, Google Pay and Shop Pay appear on the site. Wallets can speed up checkout on a phone and avoid re-entering your address for later orders.

Does the payment method affect refunds?

Refunds go back to the original payment method, so a PayPal order is refunded to PayPal and a card order to the same card.

1. Pick the method you use most.
2. Approve any bank security check.
3. Keep the payment receipt.

How Do Sets and Spare Parts Fit Into One Order?

Sets often carry a reduced price already, and adding spare heads to the same cart shares the shipping and the code. The points below explain what this means for your order.

What do sets include?

Examples include Glossy Hair & Silk Kit, Pure Light Transformation and Golden box. Some combine two LED devices, while others pair a styler with care products for the same hair routine.

Does the code work on reduced sets?

In our cart test on 18 October, the Glossy Hair & Silk Kit at €402.95, already below its €502.95 reference price, dropped to €362.66 after the code.

Is a set always better value?

Only if you will use every item. Add up the single prices of the parts you really need and compare that with the set total.

1. List the items you need.
2. Compare single and set totals.
3. Apply the code to the cheaper option.

Which spares are listed?

The shop lists replacement nozzles for MIGA, MIGA PRO, MIGA BLACK and MIGA NEW, brush heads for MORI 2.0 and MORI BLACK, and attachments for HIGE and HIGE PRO.

How often should you replace them?

Product pages recommend replacing nozzles and heads regularly for hygiene and cleaning power. Many dentists suggest changing brush heads about every three months.

Should you add spares to a device order?

Adding a pack to the same cart shares the free shipping and the code, which works out cheaper than a separate small order later.

1. Note which model you own.
2. Pick the matching spare pack.
3. Add it to your next device order.

What Happens to Shipping and Delivery?

Shipping was free at our last check, and the policy sets out processing and transit times for international orders. Here is what the official pages say.

What did our test show?

On 18 October we placed a device in the cart and requested rates for addresses in each Gulf country and in Egypt. Every one of them returned a rate called Global at €0.00.

Is express shipping available?

The shipping policy says express options can appear at checkout for faster delivery. Any extra charge shows before payment, so you can compare it with the free option.

Can the free rate change?

Shipping rates belong to the store and can change, so check the delivery line at checkout before you enter card details.

• Fill the cart.
• Enter your full address.
• Check the shipping line before paying.

How fast are orders processed?

Most orders are processed within one to two business days, counted Monday to Sunday. Busy seasons and holidays can stretch processing, so order early before big shopping dates.

How long is international delivery?

The policy gives 7 to 14 business days for international orders and 3 to 7 for domestic ones. Customs checks in your country can add a few days on top.

Which carriers deliver orders?

WAU names UPS, FedEx, DHL and USPS and picks the carrier it considers safest and quickest for each parcel.

1. Order at least three weeks before a gift date.
2. Watch for the shipping email.
3. Keep your phone reachable for the courier.

What If You Need to Return an Item or It Arrives Damaged?

The 30-day return window and the damaged-item rules both start with a short email, so keep your order details close. The details below help you decide quickly.

How long do you have?

You have 30 days after receiving your item to request a return. The item must be in the same condition you received it, unused, with tags and in its original packaging.

How do you start a return?

Email [email protected] with your order details. If the return is accepted, WAU sends a return shipping label and instructions. Parcels sent without a request are refused.

Does the discount affect the refund?

The refund follows the amount you paid, so a discounted order returns the reduced total rather than the full listed price.

• Keep the original box.
• Request the return by email first.
• Wait for the label before posting.

What should you do on arrival?

Inspect the parcel and the device as soon as it arrives. The policy asks you to contact WAU immediately if the item is defective, damaged or not what you ordered.

What evidence helps?

Take photos of the outer box, the product and any damage before throwing away packaging. Include them in your email so the team can evaluate the issue quickly.

Is the device covered by a warranty?

We found no separate warranty page, so ask support about cover for your device and keep the reply with your order email.

• Open parcels the same day.
• Photograph any damage.
• Email support straight away.

How Do You Use Your Device Safely After It Arrives?

Every device page lists its own limits, and a simple weekly routine makes regular use far easier to keep up. The points below explain what this means for your order.

Who should avoid certain devices?

Microcurrent and EMS pages list pacemakers, metal implants in the treatment area, cancer and pregnancy as reasons to avoid use. Scrubbers should be kept off sunburnt or broken skin.

How do you start safely?

Begin on the lowest setting and shortest session, and test a small area first. Stop and seek advice if redness, pain or irritation lasts after a session.

Should you talk to a doctor?

If you have a medical condition, take regular medicine or are pregnant, ask a doctor before using any electrical or light-based beauty device.

1. Read the warnings on the page.
2. Patch-test a small area.
3. Increase settings slowly.

How often should you use each device?

LED masks are suggested for 10 to 15 minutes a day, while MIRA is suggested three to five times a week. Follow the timing printed on each product page.

What should you do before a session?

Cleanse the skin, dry it and apply the gel or serum the device requires. Microcurrent devices need a conductive gel, while LED masks are usually used on clean, bare skin.

How do you track results?

Take a photo in the same light every two weeks, since gradual changes are easy to miss from one day to the next.

1. Pick fixed days for each device.
2. Prepare skin before each session.
3. Compare photos every two weeks.
