How about this for a cross promotion. Burger Kings in Japan are selling a 7 patty Whopper to commemorate the launch of Microsoft Windows 7.
For sale at a special price of ¥777 (@$8.50) for the first 30 customers each day and then sold for the normal price which is just over $17. Personally I’m not a fan of Burger King, but why can’t we ever have cool cross promotions like these?
