Ebay

So I have been searching Ebay lately for a few things on our wish list as we wait for some extra money to come in. I have found in my search that people are paying higher prices sometimes on Ebay! I cant believe people would do this. Are they paying these prices for convience or just because they want it now and maybe cant find it at the store. Im seeing some cases people are paying as much as $50 more for an item that you can get in stock at Target! Ebay is awesome, dont get me wrong. I guess I just use it to get unique items you can no longer find in the store or to get current items for cheaper prices.
