I booked a shoe of 499 and when I reached the payment section I reduced my amount by rupees 100 using the 5000 reward points, and hence my payable amount was
399+ 49(shipping charges)= 448, I was okay with the order amount and I placed the order.
But when I checked my email got a mail from fashos.com where i was shocked because the amount payable was 558 Rs, when I contacted them they said like " you might have not redeemed the rewards in right manner " I was frustrated and hence cancelled my order.
Those rewards all for grabbing purpose. so please be careful friends.
