What you need to do after entering your first coupon code is to click "apply."  The box will empty so that you can insert the next code. Click "apply" again and repeat the process. When you reach the last page, you should see that all the codes have applied successfully.

If you continue to have difficulties and you are ordering from the US site, please type your gift certificate and / or coupon codes into the comments box at check out, and we will make the necessary adjustments before your card is charged.
