The first thing is that they provide very good service and support for there customers.
I was buy many products from snapdeal from 5 year ago in this time perido no one product was cracked or old or used.
they are make littel problem on delivery but other wise good
there are many awesome and usefull features both in app or websiteso there no doubt both app and web are useful.
reliability is awesome
so I rate snapdea 5/4.7
