That sucks. The thinking in my area seems to be - OK, no sale of a gun but - they are oiling the wheels of customer service and maybe will get a sale another time. Plus it can be useful to ''sweeten a deal'' by perhaps just buying some ammo - or consumables.
My local guy has been great altho I have bought quite a bit from him - he used to charge a mere $10 but now wants $15 - still not bad IMO.
If you wanted to be FFL then yeah - has to be storefront and trading business (proveable thru paperwork) - doubt transfers only would cut it.
Sorry you seem to have such a transfer vacuum.
