Don’t flip-flop on this deal

Need a shoe fix but you’re short on cash? Run over to Old Navy on Saturday for their annual $1 flip-flop sale. For the price of a McDonald’s combo meal, you can wear a different pair of kicks every day for a week. In stores only; the nearest location is in Metro Pointe at South Coast, 901 South Coast Drive, Costa Mesa. Crowd haters can check out oldnavy.gap.com, where flip-flops are $1.99. Top off your online purchase with a cash-back program like Ebates or Bank of America’s Add It Up. (Bonus: New Ebates members will receive $5 after making their first purchase.)

Pac your sleeping bag for this one
