I question your commitment to sparkle vision... I mean the free market.El Dingo said:Ahh, the free market demonstrates supply and demand once again! Way to support capitalism, Grams!
This is an inversion of the supply and demand curve, since the Grandmother isn't attempting to sell the thing for maximum profit. She's selling it for far less than she could (given that a new one retails at twice as much as she's selling it). True supply and demand would require that she offer the Xbox she has for the same price (perhaps a bit lower) than a retail establishment, thus ensuring maximized profits.
