Just a heads up to everyone here. Used this earlier this week to buy parts for my wife's car. First time I ordered 160 dollars worth of parts and paid 115 at the after using the VISA coupon code. Last night my walmart everstart battery quit accepting a charge on my wife's jeep. I wanted to get a optima dry cell battery but decided to look online first. Normal price is 187 for 1 battery. I placed 2 separate orders for 2 batteries using the coupon code visa each time to save 50 bucks, one red top for her car and a yellow top for mine. Walked away paying 127 for each battery. I paid for it online, chose in-store pickup and picked it up about 30 mins after ordering and I'm, saving close 25-40% easily. If you're looking to do a tune-up or got some parts on your cars that need fixing now may be to time to get those parts discounted.

I know everyone on here makes six figures but I got a family and have used coupon codes/coupons and other discounts on probably about 70% of all of my purchases recently. Times are tough and little deals like this keeps your wallet filled up with your hard earned cash. Hope this helps guys.
