There can't be a rule for the price. It depends on the seller/buyer. If you don't wanna sell or buy at that price, then please leave.
To the topic starter: 3$ is a bit low IMO. Best of luck buying accounts (y)
The seller buyer concept is mostly affected by sellers who lower their price to sell their stuff. And buyers take advantage of that. There will be a time when rs will ban those accounts which are sold at lower prices or something like that..or may be stop converting points for new accounts....
You better get out of business then if you want to throw away your shit..
