I frequently purchased items from the GoodWill online auction for several months. Then I noticed several items would reach astoundingly high prices well before the auction was set to close. Similar items would also reach unrealistically higher sales than the same exact item listed on ebay or other comparable auction sites. Then I started to study particular items that would bring the higher prices. Interestingly enough, I noticed that the same items were re-listed over and over again, and the same bidders would continue to win each auction.
It didn't take long for me to figure out that the GoodWill staff were deliberately shill bidding from private accounts in order to fraudulently inflate the prices. When an item did not bring the desired prices, a goodwill staff member would outbid the high bidder, so they would not have to let the item go for less than expected. Who do they think they are? It doesn't take a genius to realize that when the same item at the GoodWill is selling for 3x more than on Ebay that something fishy is going on. Especially since Ebay consistently gets more traffic and should not be outdone by such a small site like GoodWill. What they are doing is fraud! They are playing off the allure of "helping a charity" yet their entire inventory is free and they still continue to rip people off. They also mark their prices up sky high, which defeats the purpose of having a thrift store intended to help the poor.
To those of you complaining about ebay shill bidding, at least (poor as it may be) they have a governing body that works objectively between the buyers and sellers. ShopGoodwill has all the control and deliberately scams its customers.
It won't be long before other bidders catch on, which will eventually lead to their demise.
