Tweet For Free TacosTaco Cabana’s Tweet2Eat promo has returned for yet another week! If you’ve never participated, here’s how it works. Simply follow Taco Cabana on Twitter, then watch each Tuesday for instructions on what to tweet. This week, Taco Cabana is looking for 800 tweets with the hashtag #tweetn4tacos. If they reach their goal, they’ll send out a coupon for a free brisket taco, to be redeemed tomorrow, Sept. 7. You can tweet the hashtag more than once a day, to help them reach their goal.
