I wanted to see if this sounds normal or if the LGS ripped me off.

I dont want to drop names but I ordered a gun through my LGS, something probably not available except online.  Normally I just buy online and pay the transfer fee but I wanted to support the shop this time so I paid about $150 more and had them order it for me.  I finally went to pickup my gun a few weeks later and after filling out paperwork he said "alright we are all set, that will be $42".  Happily gave him my credit card without complaining but then he said "cash only" - damn near lost my cool at that point.  I asked why I was being charged a transfer fee since I bought the gun directly from them and he explained I didn't buy it from him I special ordered it.  I had to walk down the road to an ATM which was quick but I left work to do this and would have brought cash if I had been expecting the charge.

I would have been fine if they charged me the transfer fee upfront.  I was willing to pay more to buy from them, but it was the last second surprise that irritated me.  Does it sound like these guys pulled a fast one on me or does this sound normal for a special order through a local shop?
