Flipkart is the only site which ships the item on same day and gets delivered within the specified time, I had ordered pendrive, books and head phones all of these were delivered with excellent condition and no problem till now as of pendrive (transcend 16GB) and headphones (frontech) are concerned its been 6-7 months using them, about books they are brand new ones.
What I like is flipkart gives you warranty receipt for the items purchased with sale date mentioned including books. So you can claim in case of defective.
The cons are bit over priced , low discount or no discount at all on few items and shipping charge compared to other online stores. Doesn’t mind spending those extra bucks you will get what you pay.
Shop confidently with flipkart.
