I Tried To Change Credit Card Info, But Won't Let Me

If Groupon won't accept your credit card, your first step should probably be with the bank to see if there's a problem. Then if necessary phone Groupon at (877) 788-7858 in the U.S. or write them at [email protected]. In the UK, you can write them directly at [email protected] or No. 1 Liverpool Street, London, EC2M 7QD; or phone them at +44(0)203 510 0410. Groupon is as responsible an operation as you'll encounter; I have no doubt that they'll resolve the issue to your full satisfaction.
