Ok, so I've secured a rather good deal on computer parts and am now looking to sell the items for a small profit. I've also had several individuals from another web form approach me and state their interest in my wares. However, I have never made an online transaction without an intermediary (ebay, amazon, etc.). How is this done? I would use Ebay, but the fees would eat into my margins far too much. I would assume that I could perform the transaction over Paypal, but what is the protocol? (eg. Do I wait for them to send the money to my Paypal account and then send the item, or is it the other way around?, etc). Thanks for the help.
