# How do I use my Foyer discount coupon?

To use your Foyer discount coupon, simply:

1. Create your account or log in to taxx.lu.
2. Choose the offer you want (Standard, Plus or Premium).
3. Add your Foyer coupon in the ‘I have a discount coupon!’ field before paying.
4. The discount amount will be automatically deducted from the displayed price.

Important: if another coupon has already been applied, you will **not be able to combine it with this one.** However, you can click on ‘**I do not want to take advantage of this discount**’ to remove the current discount and enter your new code.
