Like GC said, "no sales tax if you live in a different state".
The transfer fee on their end is also untrue.
The transfer fee on your end is pretty standard (although prices in different ares vary greatly), and is understandable considering the cost to maintain an FFL.
I've bought a few rifles from Buds.
Good prices,,, slow shipping.
I didn't wait until I needed the gun tomorrow to order (not saying you did) so the few extra days wait wasn't a big deal for me.
Hopefully your gun will show up soon, and the excitement of a new firearm will ease some of the pain.
Luck
