It's quick it's easy shopping from the comfort of your arm chair. I'll shop local brick & morter then hit GB and Ebay I even check Midway to see what retail is. It's usually cheaper when you factor in no tax and delivered to the door. BTW I'm in CA so most stuff isn't in stock anyway.
Buyer beware! That is something many do not understand. Know the going cost of whatever you are bidding on. Know what you are willing to spend and also, in most cases with firearms, you have to have it sent to a FFL...their cost of tranfer also is something that must be factored into the overall price you are willing to spend.
