I am the regular shopper on Flipkart and I am happy with their services. They have the fast delivery and their customers service is top class. The product price is also average neither high nor low. But I dont like their sale strategy, they should learn something from amazon.
Sometimes I feel like I have been cheated during the sales because most of the product price are increased before the sale and on the day of sale, they give discount on them. So the final price is approx the same as on normal days. Otherwise they are the best in all other categories, thats why they are the no. 1 shopping site in India.
