I think that first link showing a guy buying for 4 keys is planning to sell later at a higher price (he has 5 G. Boonies in his backpack). That said I'm not sure if one or two sales justifies that the G. Boonie should be priced more than 4 keys. If it's going to get an increase I believe it should be 3-4 keys.

Not happy with the size of that price range, but I'll accept it due to the inaccuracy of the old price.
