Are you shopping on AliExpress for the first time?

The process is via the AliExpress mobile app, where most people shop. There are two key things: don’t use Buy now and enter the coupon only in the order summary, in the field Promo code. After you click Pay now, you won’t be able to add it.

1. Copy the code and click Use discountIn our article, copy the coupon and click the button GET DISCOUNT. The link will take you directly to the product in the AliExpress app.
2. Use Add to cart instead of Buy nowOn the product card, scroll down and tap Add to cart. Don’t use the Buy now button—you’ll skip the cart, and later you won’t have anywhere to enter the coupon. Before that, double-check the variant: the color, the version, and whether it ships from an EU warehouse.
3. Through the cart, go to CheckoutA pop-up will appear: Added to cart! — tap Check it out in it. If it disappeared, open the cart with the icon at the bottom right. In the cart, check the product and quantity, then click the red Checkout. Only the items marked with the red ring will be applied.
4. Enter your address and card, then look for Promo codeIn the order summary, first fill in the delivery address and payment card at the top. Below them there’s a line Promo code — expand it with the arrow on the right.

   

5. Paste the code and confirm ApplyIn the field Promo code paste the copied code and click the black Apply. The code is case-sensitive and must not contain spaces.

   

6. Check the savings and payIn the Summary expand the line Saved — you’ll see the applied coupon there as AliExpress coupons/codes. Only when Total is really lower, click Pay now.

   

Apply the discount already at the order summary. After you click Pay now, you can no longer add a coupon. If Apply shows an error, the code has either expired, doesn’t apply to your items, or the order doesn’t meet the minimum amount.

The Store Coupon also goes in the same field. — a coupon from the seller itself, which isn’t always available and changes from day to day. AliExpress coupons can’t be combined, so try both and go with the one that gives you more. Coins are added automatically.

This is what the product looks like in the detailed video:

A stylish kitchen gadget in two colors with water filtration!

Right from the start, you can see the Chinese manufacturer put effort into the design. The water saver features rounded edges and a matte surface finish. The entire construction has dimensions of 10 x 6 x 11 centimeters, and it’s compatible with most standard faucet taps.

Of course, it’s a kind of add-on for your faucet. This device not only helps you save on water usage, but also offers filtration. The manufacturer’s filters are replaceable, so you can enjoy safe, clean, pre-filtered water as soon as you turn on the tap.

Two performance modes and a replaceable filter

The filter housing is made of stainless steel, and one piece of the integrated filter can last from three to six months of regular use. The filter material is made from coconut fiber, with an additional carbon layer.

This attachment, which transforms your faucet beyond recognition, has two modes. One of them provides maximum water flow for quickly filling, for example, pots while cooking. The other is a gentle “shower” mode you can use for washing dishes or for regular rinsing of food.

A compact box that will be delivered to your home contains the water-saving device itself, in your selected configuration and color. You’ll also find spare filters (4x), as well as a set of rubber seals for proper insulation and an installation guide for your bathroom faucet, in English.
