Starting now and running through December 18th, McDonald's locations are offering a free Coca- Cola glass when you purchase an up-sized extra value meal! It's confirmed that most locations in Utah {if not all!} are participating. The promo does run until 12/18, however it's also “while supplies last,” so if you're incredibly excited about this offer, I'd head on over there soon.
In the past they've offered a different color each week, I haven't yet heard if that's how they're offering them this time. I'll let you know!
Also, be sure to use a coupon from the mail a few weeks ago! As long as you're buying a value meal, you might as well save $1!
