In true frugal fashion, I’ve picked up loyalty cards to all sorts of stores during my travels. Somewhere in my wallet is a Fry’s Shopper Card from the last time I was in Arizona, as well as a punch card for a coffee shop in London. Today, I ran an errand for my dad at the grocery store Tesco, and picked up a Tesco Club Card while I was there. With Tesco’s system, you earn 2 points for every £1 you spend, and after you collect 150 points, you receive a voucher for £1.50 off your next purchase. I can’t imagine I’ll ever spend enough at Tesco to earn any vouchers, but it doesn’t hurt to add another rewards card to my arsenal – hey, you never know when they’ll come in handy!
