Yesterday, my friend Crystal told me that she had some friends call her and ask her if she wanted to go out to eat for supper. She buzzed through some of the restaurant deals and group buys, recommending Sequoyah Grille, a local restaurant that had posted a group buy certificate. She and her friends were able to dine out at about half of the cost of what it would have otherwise been. Most often I buy from sites like Living Social and Groupon ahead of time, but she inspired me that you can use these for last minute discounts, too.
For other tips on dining out at a discount, check out this post that I wrote a while back.
