Coupons.com has a coupon available for a free Fruitista Freeze from Taco Bell with any purchase. They sell tacos for, what, $0.79? The coupon only appeared when I entered my zip code, but in case your zip doesn't work, give 80002 a try. Did you know that's the zip code for Arvada, CO? It's the eighth most populous city in the state, 235th in the country, and wow I'm spending way too much time on Wikipedia now.
