We have a shop here that is the same way. I asked him if he could make more profit ordering a gun for me and he said "no, you order it and send it here and i'll do the transfer (for 25.00) and that will be cheaper for you"
so last week I needed a chamber reamed (new 2 groove barrel I installed on 1903) he quoted a price, and when I came back (less than 2 hours later) to pick it up I told him "I don't think the price you quoted me was fair, so i'll pay you (10 dollars more than he had quoted me) and not a penny less"
he said he normally doesn't dicker on price, but this time he'd make an exception.
