Apart from Ebay.in, there are very places where you can buy computers/accessories online in India. This makes it very difficult to do a price comparision with a dealer/reseller.
Came across this website (A bangalore based dealer whose shop is in MG Road.) and is quite comprehensive. The pricelist spreadsheet is very useful and informative. (Look for the price list button on the right hand side on top).
The items do not have specifications listed, which I see is the biggest shortcoming on this website. Hope they will improve the site soon.
