"Assured 100% money back!" screamed the e-mail I got, claiming that if I shop at IndiaPlaza.in for any amount, I would receive a voucher for the same amount. So I read the fine print.
The fine print is that the voucher is only redeemable against a purchase at least five times its value.
So suppose I spend Rs X. I get a voucher for Rs X, but can redeem it only on a purchase of Rs 5X. So I spend a total of 6X, and get X back: a discount of about 16%. (And that's in the best case that I find something worth buying that costs precisely 5X.)
Wonderful what these marketing minds can do with mundane things like a 16% discount.
