We all know that you pay a little extra for items at a store, but you don't always know how much. Engadget has a list of the costs vs retail price for the Wii and it's accessories and games come launch day. Looks like peoples in the retail industry are getting pretty stoked about the Wiis about to make it into their respective stores. We got our hands on the CompUSA hardware / software markup sheet for Nintendo's new console, as well as some spy pics of some Target Wii endcaps and the variety of accessories those will be stocking, as well. No, we're not that hard up for stuff on the console, but we do think that $12.50 is a pretty weak margin on the console, while, as expected, games, and accessories have a much fatter profit for retailers.
