Burger King offers a Whopper Sandwich for 1 cent when you order via the Burger King app... within 600 feet of a McDonald's location. While this is likely the most blatantly troll-faced offer we'll ever list, it's also probably the best price we'll ever see for a Whopper. The deal is limited to one sandwich per customer. Comment below with a solemn promise to be responsible with this power, and not subject McDonald's employees to even the slight hazing they receive in Burger King's promo video.
There are plenty of great ways to spend your money, but you can safely leave these products on the store shelf.
