My Ebay Addiction

What should I do with my ebay addiction. I can’t stop myself from buying things which I don’t even need! There are many items listed where the price is much lower ( which includes the postage too) than the market retail price. How can I let go of a good bargain? So I am compelled to bid. There was a time when I used to bid to win. The last few seconds decide if you would win or loose, so I would be glued to computer screen, anxiously watching the seconds ticking and if somebody bid more than me, I quickly increased my bid.
Now at least I am sober on that account. I don’t bid above the price I have set for the item. But still lots of items are making their way into my house, which have no or little use. Is there any sanitarium for compulsive ebay shoppers?
