All salespeople in every shop have negotiation brackets (well perhaps except grocery supermarkets) for most products and are willing to go down on the price if that may encourage you to buy. The negotiation wiggle space is normally included in the price and yeah, they do know you’re uncomfortable haggling and will go out of their way to not discourage you from purchase.
Also, but this is something I only heard from a colleague, you can negotiate up to 40% off if you convince them to purchase the product using their employee discount (so bulk price) and split the difference off the record.
