They're calling it the "eBay Whopper Shopper" promotion.
Under its terms, customers can get on eBay and pre-order a Whopper with either a chicken, vegetarian, or lamb patty (no beef since it's India) for a promotional price of 128 rupees (~$2.08 US) and get a physical voucher (by mail) that can be redeemed for a Whopper and a free Whopper T-shirt on November 9th at the burger chain's first Indian location, which opens that day in New Delhi.
While it seems a bit weird to pre-book a fast food burger ahead of launch, it does generate a fair amount of buzz. Plus, free T-shirt!
