pfft, walmart has industry setting prices! well they used to anywho, they have lost a bit of their hold on the market, mainly due to meijer coming of age... but having checked walmart prices, compared to best buy, eb/gamestop (same company), and other game buying places, the prices are all the same, 130 bucks for a ds lite... but that is american, he is australian... so eb for whatever reason has them from 180-186 depending on which one you go to... bigW (walmart australia) doesnt seem to want to budge on a 199 price tag tho they will price match... tho anyone just about will price match, or lower the price if you simply ask... funny you can haggle in any store here just about...
bottom line, dont pay more than 180 for a ds lite (in oz)
