If you are heading to Friendly's anytime soon you may want to join their BFF Club HERE. You will receive a coupon for a free 3 scoop sundae w/ purchase of an adult entree when you do! My coupon is good till 8/27.
Here's a nice $1 off any Eddy's Slow Churned Shake or Smoothie coupon. Some people are reporting these are on roll back at Walmart for $1 = free though rollback can vary region to region. If your area sells Dreyers instead of Eddy's here is the same version of the coupon but is Dreyers brand instead of Eddy's. Note: a small picture prints under the coupon.
