I'm not sure for GA, but the Goodwill's in California are all under the same direction: They are NOT a thrift store anymore but a RESALE store. They get brand new merchandise from TARGET (they have an actual contract with them) after it hits the 75-90% off mark. Goodwill then re-sells Target's merchandise at about 40% of the original price, whether it's missing pieces or was a display model or whatever. Sometimes Goodwill will just stuff whatever contents they have into the original box and then claim it is "new", charging almost the same price as Target's original price. Now, Goodwill here still accepts donations but they will look up just about everything on ebay before it hits the shelves so they can jack up the prices. Sometimes they even print out the ebay seller's page and put it next to the item to show you what a "good deal" you are getting at Goodwill. Of course, these are very high "BIN" prices from the same idiots on ebay that we all know and love who keep on trying to sell 2600 PacMan, Space Invaders, Golf and Defender for the low BIN price of $25 each and NOT what has actually sold.
Goodwill's selling practices are now despicable. Only every once in awhile are you able to find something that makes it out to the shelf without first being looked up on ebay or locked behind the "collectible" glass at outrageous prices because the workers were either lazy or they just missed it.
BTW - most of this info is NOT my opinion. I interviewed the regional director for Southern California a few years ago after I started noticing the ebay printouts and the Target merchandise (which was being sold for MORE than what Target's last price was) and he straight up told me that this was now Goodwill's SOP.
Goodwill as far as I'm concerned can suck it. I hardly ever shop there any more. Most of their employees are very rude and don't know WTF they are talking about anyway. Salvation Army does a better job at least where I'm at though their selling practices are sometimes underhanded as well.
