Old Navy offers a free birthday surprise (I think this means coupon) on your child's birthday. From their homepage, scroll down to the bottom where it reads "Sign Up and Save." Of course you'll have to enter in your basic contact info and e-mail address, but you can opt to sign up for e-mails and deals from Old Navy's affiliates (Gap, Banana Republic, etc.).
TOYS R' US
This is the coolest idea - Geoffry the Toys R' Us mascot will call your child on his/her birthday to leave a message. You can select whether you want him to call in the morning, afternoon, or evening. And your child will get a free gift card.
Receive birthday coupons during your child's birthday week.
Sign up for a free kid's meal - just FYI, you have to print a form and mail or fax it in. It doesn't appear that they have an on-line submission form, but you get a card for a free cookie just for signing up.
This is for my little friend Ansley....If you sign your child up to be a Waffle House Regular (which she is!), then they'll enroll you in the birthday club and he/she will receive a special birthday present P.S. - It's Waffle House's 55th anniversary! I don't think they've aged a bit!
This is a really neat site - you can sign your child up for the Mini Moe's Birthday Club and receive a free kids meal during his/her birthday week. When you sign up, they'll calculate how many days until your child's birthday (282 for McCord!) and it will tell you about what happened on that day in history and famous people who share their birthday (FYI - on McCord's birthday in 1847, the US Post Office released its first adhesive stamp, lick em' stick em'. He also shares the same birthday as Princess Diana). Visit their site for a free coloring page and on-line birthday games like tic tac toe and memory.
