Shopping in Auto Parts Warehouse is so easy. The site is user friendly and the customer assistance is so helpful. I never had any problems with them. delayed deliveries are just normal. I mean all online shopping experience those hassles. They're not really a BIG DEAL. Besides, Auto Parts warehouse always make up for late deliveries. Like what happened to me one time. My air filters didn't arrive on time so they gave me a discount coupon for my next purchase. See what I mean? They really are GREAT.
