I have seen that auction site before... it does seem pretty unfair. If they are getting them as donations from the local area then consumers in that area should benefit. There are like little pledges on the windows that say something like employees can't hold, buy, and I may be remembering wrong but I think it says what's donated there is sold there.. but I may be wrong... maybe it varies regionally.

It seems pretty counter intuitive too, at least my Goodwills in the area tend to be fairly overpriced on electronics/computer items, at least compared to say eBay..
