Out of curiosity, I checked for a staple gun at Sears on-line. They listed three Stanley aluminum staple guns; all look identical, but the prices, model numbers and item numbers are very different. I tried other on-line sites, and couldn’t find a match. This is a popular item. I checked Costco. Their staple gun was model number 189023 and cost $24.99. It sounds to me that everyone is trying to confuse the consumer and manipulate them. I find similar differences in model #’s for other tools as well. It may not be illlegal what they are doing, but IMO it is definitely a lack of personal integrity They join the ranks of used car salesmen.
