You'll have to be quick!
You can now collect a free Coca-Cola collectable glass when you purchase an Extra Value Meal from McDonald's at participating Walmart stores across Canada.
Depending on availability, the glasses come in a range of colours including purple, green and blue.
However, there are some restrictions as breakfast Extra Value Meals, Happy Meals and McPicks Meals are excluded from the McDonald's offer.
The offer is available for a limited time in select stores across Canada - here is a list of all the stores closest to you.
