Ruby Tuesday has a deal on gift cards, when you purchase directly from them. For every $50 in gift cards that you buy, you will receive a $15 bonus card. That amounts to a discount of about 23%. But the bonus card comes with limitations. It can only be used from January 2 to March 5, 2020. You’re also limited to using just one per visit, so if you get more than one bonus card you will need to use them in separate visits.
