Crazy enough to be caught in retail outlets the day after Thanksgiving? If you're in the States, you may be interested in 4 color rebellion's compilation of Black Friday Game Sales.
Of particular note is several retailers offering Game Boy Advance SP units for around $50. In Wal-Mart's case, at least, this sale is limited to the older front-lit models only and doesn't extend to the new, brighter backlit models, so watch what you pick up off the shelf.
Other deals of interest include Nintendo DS juggernauts Nintendogs and Mario Kart DS for slightly reduced prices, as well as numerous other titles for all current Nintendo platforms. Nothing terribly outstanding, but you take what you can get, eh?
