I have often purchased from letsbuy.com. However, I write here about a recent purchase, more since this was a high value purchase (Rs. 38, 000). They offer good combo deals. E.g., the freebies offered along with "canon 1100d+zoom lens" actually made huge economic as well as natural sense to me. I got a digital photo frame + good quality tripod + Class10 16GB SD card along with the deal. Effectively, I won’t have to make any other investment for at least the next 2 years on my photography pursuit, because of this deal. The only problem with the site is that at times, it tends to delay the shipment. In case they are able to improve on this, then the purchase experience will actually be a delight.
All the best.
