Yes. I have found a great disparity in pricing of guns.
I wish there was not the Federal limit on out of state handgun purchases as I often find good deals, especially used handguns, when I am out of state.
I checked my area, Tampa bay, and I found the best price I could. I probably could have shopped more from the on line sites and had it go through my local FFL but that is a hassle at times. And by the time you pay shipping and the transfer fee you haven't really saved much if any.
