1) It's addicting!

2) In Selling: When your items are getting bids, you get the same feeling as if you've just won a hand of Blackjack. You feel like a WINNER!

3) In Selling: Once you've got the money in your paypal account, you feel this HUGE urge to go bid on a designer handbag (or whatever you fancy) you've been dieing to own!!

4) You spend as much time on ebay as gamblers spend on gambling websites!

5) When you get a GREAT deal on an item, you feel the need to tell friends about it (as a gambler would if they got a big win).

6) Sometimes you lose!! IE buying an item not as described, your item doesn't sell, you don't get what you were hoping for out of a sell, etc.... just like gambling!

I just realized these things after someone was telling me a story about there trip to Biloxi! Funny... but true!
