Last year, I saw a lot of companies doing this and I’ll keep rounding them up as I find them. Here are the first two:
Texas Roadhouse – Get a $5 bonus eGiftcard with $30 Gift Card Purchase online
Outback Steakhouse – Get a $20 bonus card with $100 in Gift Card Purchases
Make sure you read both sites for requirements/exclusions and the dates in which the bonus card can be used.
You could always keep the bonus gift for yourself and pair it with a coupon for savings on a night out for your family! If you have a favorite restaurant, check online over the next week or two as you might see a deal like this pop-up for them, too!
