Computer prices

Apparently most of us are rather selfish and 'cheap' and I learned this the hard way when I went window shopping for computer parts (Ree Nee's pc broke down) and you can see the major difference of prices of parts between Penang and KL can you actually give a reason why? I know I can't and just in case you didn't know, thumbdrives in TESCO sometimes are cheaper than those sold in the PC shops! SO, before you buy anything make sure you do a bit of window shopping first!
