Just in time for Mothers day weekend, Tim Horton drops something called the "mother" of all coffees as they are showing their appreciation to all the moms out there by offering a new, "Mom-Sized" iced coffee.

This iced coffee holds nearly an entire pot of coffee at 520z..Tim Hortons Mom-sized iced coffee is available at select restaurants in Buffalo, Columbus, Detroit, Toledo, & New York City only on Mother’s Day. (Don't forget, that's Sunday) That's not it you can also purchase special Mother’s Day themed donuts for Mom at participating restaurants throughout the U.S.

They are asking moms to Share thier Mom-sized iced coffee on social @TimHortonsUS on Instagram, Twitter, and Facebook.
