Ebay.in — Bogus coupon code

Address:	Mumbai City, Maharashtra, 590002
Website:	EBay.in

I recvd an email from Ebay.in about daily/promotional offers and also a gift coupon of 100Rs ; it would be applicable on min purchase of 200Rs. So I decided to use this coupon and added a Xiomi Earphone worth 210Rs, I added the coupon code after which the Final Payment is 110Rs. But when I clicked on Pay and selected NetBanking, some error was displayed and page was refreshed; I further continued with my shopping bag, but now this time Ebay site was displaying to use this COUPON after 1 Hour, So I tried it after 1 Hr but still same error image.. Then I checked without coupon code, then clicked on Buy, then Internet Banking, then banking site page was opened, But when I try with Coupon COde it was showing Error.. I just want to ask if EBAY dont want to its products on Discount Prices to its Customers, , THEN WHY EBAY PROVIDES BOGUS COUPON CODES to it customers???????????????????. Just to increase their TRP on thier Websites???
