I love PFCHangs, so I tried it. I joined their Warrior Club and got 10% if I go this month and a free order of lettuce wraps.
I joined the Amici club at Carrabas and got a coupon for a free appetizer.
Duncan Donuts has a club you can join for free stuff, but I passed since yeah, donuts? I can skip them. https://www.dunkindonuts.com/CreateAccount.aspx But, if you can't skip donuts, you should know that this Friday they are giving away a free donut with beverage purchase. I don't think you have to join the club for that.
If you join the club at Blizzard Fan Club at Dairy Queen, you get a free blizzard. http://www.dairyqueen.com/us-en/
I have never been to Qdoba, but I love mexican food, so I went to their site and of course, they have a club to join. I get free chips and salsa. http://www.qdoba.com/Email.aspx
Oh the Border is one of my all time favs, so I tried them. Yep, joined the club and got free queso: http://clubcantina.ontheborder.com/clients/ontheborder/survey.htm
Then I went to Fridays because my friend The Lunchlady already has a card there and gets great discounts and free stuff: http://fridays.com/gmms/GiveMeMoreStripes.aspx
I think I could do this all night. Every website I went to, got me something free. So I guess my advice is, don't go anyplace before checking their website for freebees!
Does this only work for food, or other things too? Anybody know?
