Ruby Tuesday's has a great gift card promotion going on now through December 31 where a $50 purchase of gift cards nets you a $15 bonus coupon that's good 1/2 through 2/28 next year. They're also offering free ground shipping with a standard online gift card purchase from December 5 - 31st. No worries about having to run into Ruby Tuesday's to grab gift cards to snag this deal since you sure won't get the bonus if you buy gift cards at a grocery store instead.
The free $15 coupon you get for ordering $50 worth of gift cards will be delivered within 2 business days of the purchase, which makes me believe that it will arrive via email (check your spam filter!) The coupon will expire 2/28/2012 and is not active until 1/2/2012.
