ebay is distributed, whereas fk is centralized. ebay is not very attractive because of incorrect listings/inaccurate descriptions/unknown sellers etc. For higher priced items this becomes even more disappointing.
Authenticity is difficult to ensure just looking at the listing(I got a cheap replica of creative ep630{which was refunded of course}).
I have good experience with ebay though. Cordless worth rs 5k was incorrectly listed and hence I had to submit it back after the delivery. This was sorted out quickly and whats more, after submitting the shipping charge receipt by email, they even issued a refund for shipping charges!
Online shopping is the only option in some cases and thus it helps even if its overpriced and monopolized.
For normal items, however online should be cheaper as better optimization practices could be adopted there.
Agree that Flipkart is overpriced, incorrect(had to cancel order because its out of stock suddenly
) but there is no good alternative as of now, sadly... (I am yet to find any other site which has items not listed on flipkart, barring a few)
We need an amazon like which has everything and is reliable and is cheaper.
