Flipkart one of the most used website by Indian user. Very relaible website rarely you would experience any fraud or dissatisfaction from this website. I would recommend this in a very positive way.
delivery time- might take a bit long but once a date is committed delivery would be done always before that not later in worst case on last date but not later
Refund process- very quick
Return policy- Very Genuine
user interface- one of best even website like amazon lags behind in this case and very easy to search a product
compare option- yes customers can compare products
price and offers- might not provide one of best offers and sale option in the market most of times but this is the only option where flipkart lags behinds.
very trust worthy
customer service- very polite and genuine
and also have customer orientwd thinking
