Flamin' Hot Chee-tos. They were once only available for a short time in MD. I was hooked, and I traveled for work. I would be in Chicago or LA buying 20-30 99 cent bags and stuffing them in my suitcase or FEDEXing them home.
Now they're finally available here, but they are hell on my blood sugar and my weight. I've since learned some moderation.
