I can’t find where to put my coupon.

If you had the chance, or the cunning, to get a coupon, then you have to put it on your cart’s first page. 

The url should be as follow : https://www.smiirl.com/en/store/cart

Below the shipping country, you’ll see “ promocode ” followed by a plus sign.
Just click on that sign and type in your coupon.

Here you go 😉
