In February I was buying Listerine at Walgreens. I was suppose to get a $4.50 Register Reward, also known as a Catalina. For some reason it did not print. The manager could not figure it out either. So I took my receipt and called the Catalina company, their number is 1-888-8coupon. They asked me a few questions, asked for numbers off my receipt and said they would look into it and call me back. The next day I got a call back, they said a Catalina should have printed, they were sorry for any inconvenience and would mail me my Catalina. I did have to wait 7 weeks for it…….but sure enough today in the mail my $4.50 Catalina came.
