today some dealers in chandni qouted me the price of amd x2 4200 as rs. 5000 and some quoted rs. 5500...i was really surprised because everywhere else i found out it was rs. 6900 somewhere while some places it was 7900...thats really strange...the guy like vedant infotech,marc infotech are quoting the prices like 5000 and 5500...are these places reliable??? and can there be this kind of price difference??
