Really good tips!
I would also recommend checking out the weekly coupons that come in the mail. Ours usually come on Wed. and are full of coupons from local restaurants, as well as, fast food.
Most restaurants offer birthday meals/desserts if you register on their websites. This is good for kids, too!

My daughter and I have birthdays this month so I have signed us up for some. Do a search for "Free birthday meals" or "Free stuff on your birthday". There's lots of lists out there.
If you have a tourist info. center near you, stop in to check out their free brochures. Sometimes you will find coupons there, too.
