There was a time a couple years back when one or two of the local FFLs (at gun shops) complained because the were a pita to get paperwork, etc from. 1 actually doubled his normal FFL fee when transferring from Bud's. My thought is that they would bad mouth Bud's because they couldn't compete with them on gun prices. I might suggest you ask your FFL his take on dealing with them prior to ordering.
I've never bought a gun from Bud's, but I have bought a few supplies from them and had a very good experience. I had a return and there was no issues (I paid to send it back is all).
