I stopped by Discount Tire last week to get my tires replaced and I could only afford a set. The following weekend I went back to get the last pair because I needed all four replaced. They returned the pair I got the week before and re-purchased them so it would cancel out and had me buy the last pair that day so that I could get the $70 rebate. They have always been outstanding when it comes to customer service! I will not go anywhere else!
