I live in Bangalore and have availed snapdeal vouchers thrice and have had different kinds of experience which I would like to share.
One was for a perfume where they had a condition of buying the product more than 2000 which was not mentioned on the website so for the rest of the deals, I made a call to the involved dealer and confirmed the charges which was fruitful for me! :)
Snapdeal is a genuine website and safe to use.I would recommend everyone to enjoy the discounts but calling the dealer would make it a safer option and would save you from hidden charges.
For the first time you can start with minimal expenses like 100-200/- I am sure you would try it again! :P
