Probably you have seen some posts for ebay seller jobs. The idea is they send you pictures + description of items, you list them and sell the items. You send them the shipping address, they provide tracking and send the item.. after the item is received, you pay them 75% of the item's price. That seems too good to be true and my question is where is the catch ? How can they scam you since you pay them only after the item is received ?
