Good morning Gesa,
I just checked and your H-P promocode is working ok. First, drag an image onto the H-P 5x7 product and then check the promocode under Options for the product. The precise promocode for your group 12410sdc needs to be entered. It is case sensitive without spaces etc. Once the correct promocode is entered, press "Enter" and the promocode box will turn pale green if correct. If not, the box will turn pink indicating it hasn't been entered correctly. Once you add it to the order, the price will change to 25 cents for the H-P 5x7.

I've attached a screen capture showing what this will look like.

Please let me know if I can be of further assistance..... and thank you so much for helping special people in need with a portrait!

Don
