Not exactly friendly. I received a circular in the mail advertising NPS. It worked and I went to this store to buy chlorine tabs that where shown on sale in the mailed circular/flyer. They had no idea what I was talking about. I asked the clerk and his response was that is what a flyer is for to bring to the store! I asked him if they had any way to look at their own ad and he said no. I would contend that the advertising is to bring me in and then they sell me something. Clearly this concept was lost on the smart mouthed guy behind the counter. Purchased the tabs from a competitor and placed this review. Pretty sure that their marketing was looking for a different result?
