I've gotten a few specials over the past year with Foursquare and I want to keep track of them so here's the first pass at the ones I remember.
Spend 10, get 5.
spend 25, get 10.
Free Sandwich on 6th Check-in.
Free wine tasting, 3 or 4 times.
Free bottle of wine, 2 times.
Free Wendy's food, 4 or 5 times.
I'll be back with more. 🙂
