Smashburger: Buy $50 GC get $15 in Smash Cash Coupons (in store only)
I received an email saying that you get 3 $5 Smash Cash coupons with every $50 gift card purchase. The $5 coupons are one per purchase, but you can place separate orders and apply one $5 coupon to each. Gift cards must be purchased in store - not available online.
Went to my local Smashburger and completed the deal with no problems. The way I see it, I can give a $50 gift that will end up costing me only $35.
Note: I don't know if this is YMMV, but it has nothing to do with their Smash Club as I don't belong, and only get their emails. The manager said it was a readily available promotion with no documentation needed.
Almost forgot, they also offer a $25 GC with $5 Smash Cash.
