Groupon USA allows you if your groupon expires to use the face value of the groupon. So if you buy groupon for 150 aed for 300 aed worth of food, you will still be able to use 150 in the store because groupon releases the money to them. Groupon AE keeps all the money until the voucher is redeemed, in hopes that someone will let it expire in which they get to keep the money. It is a scam allowing them to place fast expiring dates on their groupons in order to steal money. When you call them they said "sorry, we can change this, the company you purchased your groupon from will not allow us to change the expiration date" so i called the company and they said they have no expiration date, that is just the one groupon issued. Long story short, every company on Groupon will give you the groupon price in-store if you call and ask, so dont purchase from them any more!!!
