Ever since writing about Groupon, Weekly Plus, and LivingSocial Deals, I’ve been hearing from more friends who have signed up for the e-mailed discounts. Suddenly, those of us in lower tax brackets are participating in the high life---massages, pedicures, and nice dinners out. The success of these sites has apparently created a healthy marketplace for even more Denver discounts to thrive. YoloDeals, a site that had a false start earlier this year, has relaunched. It offers daily deals, with an added bonus: 10 percent of every purchase is donated to a featured local charity. Another website, Denver Perks, offers a wide variety of half-priced deals, from heating and air conditioning services to discounts on riding alpine slides. Deals are updated weekly and remain active until a certain number are purchased.
