FREE Carwash on Birthday at Cobblestone ~ & Free Express Car Wash for Signing Up!

I was just redeeming my Groupon deal ($20 for 3 car washes — still going on) at Cobblestone's website and was reminded of a deal I'm not sure I've told you about . . .

If you sign up for their rewards club, you will receive a FREE basic, full service car wash on your birthday.  (It's good the day before, after, or on your birthday.)  It also says you will receive a free express (drive-thru) car wash for signing up.  I can't test this since I'm already a member, but I'm guessing they will email you the coupon.
