Best Buy Computers

I work with video quite a bit and it's important for me to get good SD cards that are class 10 so that i can shoot my video stuff properly. However an SD card of this nature cost me recently $90 at one shop in Sim Lim. I found the same thing in best buy computers for $35!! I couldn't believe the price difference and the initial store where i made my purchase from, was actually one level above....isn't it supposed to be the higher you go the cheaper the goods become? These guys have some ridiculously fabulously cheap deals for SD cards, desktop and laptop rams, external hard disks and more. Call them and find out if they have what you are looking for and how much it costs.
