Question about upgrades

[FailedPure]

Hey I have a couple of questions about account upgrades.First where do upgrade sellers get there upgrades and If I got a prepaid cc could I start selling upgrades by buying the upgrade after the trade?Example:Customer A wants to buy a upgrade from me. He pays me and I go onto his account and buy the upgrade for him. Is this allowed?
Thanks in Advance

hmmm some people buy gamecards for online and i think they get % off sometimes, yes you can do that they can pay you and you will upgrade their accounts ...but make sure its not a continuos membership if you use your cc

Depends on the seller and where they live. Some do upgrades via sms meaning you type in their phone number and they receive a text and have to confirm it to give you membership ( which I feel is the safest way to upgrade) Some take advantage of currency exchange rates when buying upgrades.
