Ebay sucks for selling. However, for buying, it can’t be beat.
Actually for buying eBay can be beat, especially for cameras and computer items, whether new or added memory chips. Just "Google" the item(s) you want and then compare prices. Many "buy it now" items include additional charges for postage.
I like to check alternate prices and sources before locking onto eBay. eBay can be a winner, though, but not always.
Their Blackthorn software is horrid and there is very little documentation out there when it develops an error code.
I stopped buying, too. Mostly because I’m in NYC, and by the time all is said and done (and the outrageous shipping prices are added in), I could probably find it cheaper in person.
