Popular giveaway McDonald's Monopoly returns to the fast food chain's stores tomorrow, but one man has come up with a way getting free stickers.

Usually to collect the stickers, which can result in prizes for McDonald's customers, people have to buy plenty of food during the promotion. However Facebook user Ryan Swain has discovered that if you ask for a large tap water, you can get your hands on the McDonald's Monopoly stickers on the cup without paying a penny.

It is not known whether the fast food chain is aware of this method, but McDonald's will probably become aware when thousands of people start asking just for tap water.
