Here are others I am aware of:
- Subway in our area has the Subway club. One point per dollar and 75 points gets you a free footlong. This replaced the stamps of years past. Not available everywhere though as I have asked while on vacation and it wasn't available.
- Max and Ermas has a club also, not as great but after 5 visits you get 5% off future dining. The % goes up the more visits you have. Not very many other offers to get you in the door though.
- Red Robin Red Royalty program
- TGI Fridays Give me More Stripes
- Landry's Select Club (Replaced Rainforest Safari Club)
- My Outback Rewards. Basically good for a free appetizer after $250 spend.
