Buffalo Wild Wings is offering a deal where you get a bonus gift card worth $5-$100 with purchase of $25 in gift cards. Alternatively, you can request a gift card via mail:
OR mail a self-addressed, stamped envelope (VT residents may omit return postage) with your name, street address (no PO Boxes), age, daytime telephone number legibly hand printed to: BWW Blazin’ Bonus® Game, PO Box 50188, Minneapolis, MN 55405, postmarked by December 31, 2014 and received by January 11, 2015. Each request must be mailed separately. No mechanically reproduced requests will be honored. Sponsor is not responsible for lost, late, illegible, postage due or undeliverable mail. Limit four (4) Coupons per person regardless of method of participation.
If you choose the mail route, each entry will cost you two stamps (one to mail, one for the SASE). Stamps are $.49 each, meaning that you make at least $4.02 in gift cards for each entry you mail, assuming you like Buffalo Wild Wings and want to eat a lot of them in January-February during the gift card redemption period.
