My small town is growing pretty quickly, and they just put in a big Autozone to compete with the local Napa and O'Reillys. They've been running specials to undercut the other guys. My biggest problem is they hired some of the most incompetent bozos they could find. I went in fishing for good deals to replenish my stash, and they had some signs for 5 quarts of QS dino and an STP filter for $12.99. I thought that was a pretty good find, so I grabbed 15 quarts and 3 filters (limit was 3). Went to check out, and it rang up $83.67. I showed him the sign, and the mananger began to ARGUE with me in front of 6 other customers that it was an old promo and no longer valid. I told him if it's on the shelf, it't their fault, not mine and asked him to honor the clearly marked price on the tag. He refused, and I handed him all 15 quarts and 3 filters and started to walk out. He tried to stop me and asked what he needed to do for me to make my purchase. I told him the minute he argued with his customer, he lost not only this sale, but all future sales. I told him this wasn't a good way to draw customers away from the other local businesses. I went over to Napa, told them the story, and they honored AZ price with their Napa gold filters.
