I'm going to chime in here on the 3% surcharge. I don't like it, but with the advent of the internet it's difficult to keep a decent profit margin in the firearms business. Every time, a customer charges something on a credit card the vendor is charged that 3%. Now they could factor that into the cost of doing business and increase their prices across the board, or they can give you a discount if you pay cash/check.
Now, I don't want to have to pay for someone else using a credit card when I buy something, if I'm paying cash. If you choose to use the convenience of a CC, then you should pay for that.
WRT local gun dealers in general, I've seen a few go out of business in the past few years and it's nice to have someplace within driving distance to shop, fondle, window shop. In addition, WRT 5280 in particular, there's not a lot of gunstores (to my knowledge) that not only have such a large inventory on hand, but are also a Class 3 with SBR's and Suppressors. The only other class 3 stocking dealer I've been to is Jensens. And while 5280's prices aren't rock bottom, I'm willing to pay a small premium to have a place within driving distance that I can pick up accessories, ammo, a gun, or some odd part I need. There is some value in being able to hold the gun you're interested in your hand and see if it suits you.
