If you were lucky enough to score one of those Kangaroo Express refillable drink cups this summer, the free refills are about to run dry.
One week from today, on Sept. 5, the all-you-can drink promotion ends.
But don't throw that cup away just yet.
From Sept. 6 through Oct. 1, you can fill those promo cups with slushies or soda or 50 cents.
It isn't free, but still a pretty sweet deal.
