When I sell small parts, there's not a lot of room or need to haggle. I can stick it back on the shelf for as long as it takes. Eventually the item will sell. Not going to cut the price in half just because some clown emails me. I have bargained with bikes when a buyer is in front of me. Guys have shown up and made deals for multiple items that have worked out.

Been in sales for years. A lot of potential customers assumed I'd be willing to blow off my commission just for the honor of selling to them. The usual line was "I have lots of friends (or associates) who will buy from you". I learned quickly that this is one of the biggest lies since "one size fits all". My response was to smile and offer them a rebate for every paying customer they would send.

"Don't you trust me?" Not if you say that to me. My answer was usually "I trust you completely. However, management doesn't trust me. Let's show them proof of what a valuable business partner you could be'.
