Whether you're looking at giving some as presents or grabbing some for yourself, the holiday season is a prime time to stretch your dollar as long as it's for currency that you can only spend at one place. A number of restaurants are offering a bonus of some sort as an incentive to fuel your holiday giving.
Please note that a lot of the bonus cards are more appropriately described as "bonus coupons" and are not gift cards. They typically have no cash value, include an expiration date, and may have other terms attached. You should check with the respective restaurants for details if you have any questions. I've listed the expiration dates where I could find them.
Some deals are online only, while others are available at participating locations only so be sure to ask before buying.
Here's a list of restaurant gift card bonuses/freebies available for the 2020 holiday season (I'll update if more come in):
