I picked up a cup on a rather cold morning for $1.99 (I still got brain freeze drinking it though). You can also get one for a buck from 2-5 PM.
If you've never tried Taco Bell's Freezes before, they're closer to Sonic slushes rather than to 7-Eleven Slurpees, which is to say they're like the day after it snows rather than the day of.
Overall, I really like Taco Bell's Sangrita Blast Freeze. The fruity flavor and icy cold makes for a refreshing treat with surprising complexity.
