Bit of a conundrum

Hey guys, I need your help in a bit of a conundrum I accidentally put myself into. So, a couple months ago, I logged into a website with a password I got off a forum. I liked the site so much, I then purchased a membership to it. Unfortunately, my cookies and saved password information was still on my computer. I logged into the site one day under the credentials I got off a forum (unbeknownst to me). I thought I was logging in under the legit user name and password combo I had purchased. So, I was browsing the site and a popup came up advertising a special the site was having. It was try these three sites for a dollar. So, I clicked it thinking i was under my own credentials. It bought the trial or whatnot under someone else's password and username. I didn't mean to do it as I thought I was under my credentials. What could/would happen in this circumstance, does anyone know?

Mostly, you just gave everyone using that same PW access to 3 more sites. How nice of you!

I'm assuming that you are worried that they will look at your records and compare them to the account you were using. That's very unlikely. Even if something does come up, all you have to say is that the account belonged to your friend and you let him use your CC to upgrade his account. But if you are really worried, I would pay the extra dollar for your own account.

Thanks for the reassurance dude. I feel bad about doing that to whoever's credentials I was using; just gotta be more mindful of that sort of stuff in the future, I guess.
