The current trend in India is e-commerce websites. MySmartPrice (a price comparison site for Indian e-commerce sites) compiled | a list of 343 websites (as of May 2012). There are more than 813 seller listings on Junglee.com. There are so many that are not listed
I found 24 websites which do the aggregation of prices from pretty old to the latest Indian e-commerce websites. I found all these through a quick 15 minute search. Well, Junglee is the most famous because its made by Amazon. A base for attracting customers towards amazon.in probably.
From my personal experiences of searching for books and buying in the last 2 months of around 10k spent in total.
SnapDeal spends a great fortune to speed up the site to everyone. Their customer service is a nightmare when you email them. They get back to you only after few days and they prefer to talk to you over phone for things that can be done on email. Adobe and Akamai services for their websites.
Infibeam still offers free shipping for any price and had a headstart on getting up 3rd party sellers.You cannot move an item from the cart to a wishlist.
BookAdda has a lot of books in stock which I needed (OReilly books and Pearson) for a fairly lower price tag and in availability. I had many bad experiences with the website like losing the items in the cart.
*BuyThePrice* was shutdown about a month ago.
Shroff Publishers displays the wishlist (w/o truncating it) and items in cart on each and every page. The shipping costs you about 30% more to the value of items in your cart. They use DTDC ( the not-so great courier company which takes 2 days to deliver a package that is < 1km away from the target). You can create a wishlist even though you are not logged in. ( No other site Indian e-commerce does that currently)
