One of good way for supplementing living cost is to make full use of "point card". Many shops from mega chain stores to local shops issue it. We"ll get some points based on how much we purchased, and receive services by points. Gift voucher, discount ticket, a bottle of wine or beer, sweets, cash.... various privileges encourage us to go the certain shops.On the other hand, yes, point cards bring merits to shops, too; customers and sales, of course. Shop owner or marketing teams work hard to attract loyal customers.
Then, my wallet is full of point cards... mmm, let me consider about it. Well, my recommendation is the sandwich card of Subway, the American big sandwich chain shop. You'll get one free sandwich by collecting 8 stamps!
