CHARLOTTE, NC (WBTV) - It is incredible how much you can save with using your rewards cards shopping. These days it seems every store offers some kind of customer reward program.
You sign up, give them some personal information, and they give you a car for your key chain that enables you the discounts.
But I found a blogger who points out the dangers of giving out those 10 precious personal numbers. Adam Dachis suggests using "Jenny's Number", 867-5309 from Tommy Tutone's 1982 hit.
I went to Gateway Village outside uptown Charlotte, and Park Road Shopping Center. After asking 9 shoppers, the general consensus was, the discounts are great, but the emails that follow, not so good.
