I have used these two sites to make a little cash. Fusion Cash is okay except for you have to wait 30 days and your first withdrawal has to be a minimum of $25. I don't use them that often though. Inbox dollars was okay, but I haven't used them recently. I have made about $30 with them.
I just find it hard to do those offers. I try to stick with things I really want to buy. That way I don't have to worry about cancelling orders in time.
Has anyone else tried these?
