And I am seriously considering putting a computer on the sales floor so customers can log into eBay, pull up bluepennylady auctions, use the BIN and pay at the front register. I bet I have a least two or three people ask almost everyday if they can bid and pay here. Well of course you can.
And you're educating them too. They've bought something on eBay.
Does seem to me you'd want to lock that computer down so it acts as a bluepennylady kiosk--that is, they can't get anywhere else on your computer, not even other eBay auctions. No clue how to do that.
'Course, if you could confine the PC to eBay only, but not just your stuff--you could open an eBay cafe. Really expensive coffee and access to online auctions.
