If you love frozen yogurt, head over to Yogurtland for its Guest Appreciation Day. On Wednesday, May 10, they’re offering an unlimited cup of the sweet stuff for just $5. You may get a special 8-oz. cup to fill, but you can pile it sky high — no limit on the amount of frozen yogurt and toppings. Go crazy! Kids will have fun trying to see how much they can tower in the cup before it topples. (Frugal families might consider letting kids share one unlimited cup to save on money…and sugar intake!) There are four participating locations — Arvada, Centennial, Denver and Littleton. They’re open from 11 a.m. to 10 p.m.
