So basically i heard its possible to buy like a "credit card" for internet purchases. Let's say you buy one for 50$, its got 50$ worth on the card for u to anonymously buy stuff on the internet. Does such a card really exist and where can i get that?
Yes it's called a virtual credit card (VCC). You can pick one up at your favorite retailer such as Kmart, Walmart, your local Supermarket, Sam's Club, your mall may even have one, etc... Be aware, you do get charged an activation fee, so $50 isn't exactly $50 it's more like $53 or something like that.
We have pre-paid cards over in the uk all newsagents stock them, check the tv part of the mirror for the ad, i think it cost five pound for the card than you pay to top the card up.
In addition to what Stroh said, there are very many online VCC sellers (granted its forbidden here in the BST).
Again yeah they have it in Canada, available both online and in many retail stores. You can also simply go to walmart or something like that and get a prepaid debit card (which is basically what this is).
