If i go to a gunshop to buy a rifle ive been looking at on the computer and they dont have it will they order it to their store for you?

If it's a good gun shop, they will.

Yep, thats how I got my .243 last spring. Like Wingbone said a good shop should do this for you.

The website should give you a list of "dealers" in your area.

They should, but like was said above the website should show a list of dealers in your area.

A good method is to use this link
http://www.galleryofguns.com/Genie/Default.aspx

You can search for your choice, see if the participating dealers have any in stock, and get an online instant quote.

The quote will give you the "out the door" price including taxes and fees. You have the ability to put a deposit on the gun and have it held until you get there. Amount of deposit required is listed in the quote.

The default radius is a 25 mile search, but you can expand that to 50 or 100 miles.
