Groupon Storing Card Details without Authorisation

Hi everyone, just came across this and wanted to share it with everyone that you should not use credit card on groupon. Maybe use paypal. Every time you make a purchase on groupon using a credit or debit card they will store your card details even without you agreeing to it. There is no option to disable it from saving. If you go back to buy something else you will see your credit card details already filled in.

YOU WILL NEED TO CONTACT THEM AFTER EVERY PURCHASE IF YOU WANT TO REMOVE YOUR CARD DETAILS FROM THE SITE.. WTF!!!

I had a chat with their support and they confirmed it as well. See below for details:

[myself] Issue: I need to add, remove, or update a credit card

[Mary G.] Hi, sunny.

[Mary G.] Thank you for contacting Groupon. My name is Mary.

[Mary G.] No worries. I’ll be more than happy to help you with this one. Please bear with me a minute or two while I’ll pull up your account.

[myself] Hi, I would like to remove my credit card details. And I do not remember saving them for future.

[Mary G.] Thanks for waiting. For security purposes of your account, kindly verify your full name, first line of your address and postal code registered on your Groupon account?

[myself] sunny lastname
[myself] xxxxxx
[myself] xxxxx

[Mary G.] Thanks for confirming. I've already updated your credit card details on your Groupon account. Once you make a purchase you will need to enter your credit card details manually.

[myself] But where do you guys have that option that saves the credit card details?

[Mary G.] When you make your first purchase with Groupon, your credit/debit card number is transmitted by encrypted SSL directly to a secure electronic vault for your convenience at the time of checkout. Please be assured that at no time is your credit card information ever stored on our servers.

[myself] You are saying its not stored on your servers, then how could I see it again?

[myself] When I did the first purchase I did not choose to save my card details.

[Mary G.] This will not be reflected on your Groupon account, sunny.

[myself] I understand it wont be reflected from now. But how and why did you guys store it previously?

[myself] Where is the option which says the details will be stored?

[Mary G.] This is on the time when you make your first purchase, sunny.

[myself] If I make a purchase today will your site save the card details again?

[Mary G.] Yes, sunny. But you can request to remove or update or your credit card.

[myself] So I have to again go through this process?

[Mary G.] Yes, sunny.

[myself] Won't use Groupon ever again and tell my friends as well in that case.

[Mary G.] Please accept my sincere apologies for the inconvenience caused.
