Not sure what pcwhizz means, but the moral of the story is to shop around. I agree that PC World's and DSG Group's prices are generally higher than other suppliers, but sometimes you can pick up a bargain. Probably incorrectly priced, so if you see what you want, buy it. I bought a 3DFX Voodoo 3500 card, (remember them), from Curries years ago that was priced lower than the 3000 version!
Its probably wrongly priced. I was there over a wk ago and they had Extigy at £99. When I went back to buy it couple of days later, it had gone up to £149, an outrageous price. Cheaper everywhere esle. Guess I missed a good bargain.
