Groupon invite follow-up question

i've decided to go with Groupon and get the offer for Photo Affection. their invites are very nice and i found one that is almost identical to the one i had created on Zazzle.

i do have a quick follow-up question:

does anyone know...

if i decide to get the groupon and i choose to print on the back of the invite... does the groupon just cover the cost of the front and i have to pay additional for the back or does selecting to print on the back void the groupon?

Re: Groupon invite follow-up question

whatever you paid applies and you pay the balance. i do it almost every Christmas b/c i'm crazy lol
