QUICK TIP: How to get a store loyalty discount without having a membership card

SAN FRANCISCO (KGO) -- 7 on Your Side's Michael Finney has a Quick Tip for you that will help you get a store loyalty discount without having a membership card!

Can a 1980s pop tune actually get you discounts at your favorite stores? I'm Michael Finney, and this is a Seven on Your Side Quick Tip!

When you go into many retailers, if they have a loyalty program, they'll ask you for a loyalty card. If you don't have that, they ask you for your telephone number. If you don't have either, you don't get the discount - unless you know this secret! It's a Tommy Tutone song. Let me show it to you...

You remember that song, don't you? Well, that telephone number's been given to every retailer in America! So when they ask you, "Do you have a telephone number?" absolutely you do: your area code and 867-5309. You'll get a discount! And is this cheating? Every single retailer I've asked about this say they don't mind.
