What do you say when someone says "Would you like a frequent customer card?" I usually respond "No thanks, I'll just lose it." When a frozen yogurt shop recently popped up in my neighborhood I was faced with the dilemma of whether or not I join the "frequent customer" club. When they told me I didn't have to keep track of one card and I could combined cards, I said "I'm in!" The result, 6 cards with 10 stamps combined, which equals 1 free 5 oz frozen yogurt. Yum!
