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.

Formill FT-21: Powerful walking treadmill with 2.5 HP and LED display

The Formill FT-21 walking treadmill offers a sturdy design made from quality ABS plastic materials, finished in a matte black look. Product dimensions are 106 x 48.5 x 10.6 cm. The weight is then 15.6 kg, which you’ll appreciate especially when carrying it around—thanks also to the pair of wheels.

You can customize the individual walking modes using the physical buttons on the remote control. You can also track your workout information on the built-in LED display.

Another advantage is the low noise level while running, which is at up to 40 dB. The running surface measures 90 x 38 centimeters, is also non-slip, and consists of up to 7 high-quality layers. It also has direct mains power supply, and there’s also an automatic treadmill reset system for the next user.

In the package you’ll find the walking treadmill Formill FT-21 itself, as well as a local power supply for the mains (EU Plug, 220–240 V / 50–60 Hz), a remote control, lubrication accessories, two wheels, a brief user manual, and the first-time device setup—in English, as usual.
