Buds is usually my go to site for price comparison but they have been getting beat by other on line sales sites. When I purchased a M&P, Grab a Gun had it for $515 shipped. I tried the "Make an Offer" but Buds wasn't accepting anything close to that.
I've priced at Bud's, but never bought from them. I have heard bad things about them in the past, and something about their whole site make-up scares me away.
I purchased my M1A from Bud's in 2008 - best deal at the time. Was going through KY (the state, not the lube) a couple years later, and made it a point to stop and check them out. Pretty unimpressive shop, their inventory must be warehoused. Nice guys to visit with, though.
