Your location isn't listed on your user title, so I'll just offer this general warning: in some states, even a good online deal can be offset by the ridiculous transfer/processing prices that you will have to pay and the effort you'll have to go through.
For example, I'm in MD which isn't a very gun-friendly state. I got a good deal online, but then with the fees I had to pay it didn't turn out to be nearly as good as I originally thought. I still made out ahead in the end, but just barely, and there was, of course, extra hassle involved. I think they purposefully want to the make the process (well any firearm purchasing process) a PITA here.
If you live in a free state, it should be easy and you will most likely get a better deal than locally.
