Frequently asked questions

How do I use a Flextail promo code?

Copy the code, go to flextail.com, add what you want to your cart and paste it into the "promo code" or "discount code" box before paying. Check its conditions first: minimum order, first order only or excluded products.

Do these codes really work?

Each code shows when it last worked, based on anonymous checks by people who use Kupoki. Codes that stop working drop off this page on their own.

Does Flextail offer cashback?

We don’t offer cashback at Flextail right now. The codes on this page work as usual.
