I do my best to support local businesses. Small operations don't get the wholesale prices that large companies do, so they will always be more expensive. The real question is how much is it worth to you to have that local business be there when you need it?
I completely understand that money is tight and spending it on guns, although fun, is still an expensive proposition. See if he can get you closer in price and go with the local guy if you can.
Totally your call, but that's my two pennies worth.
“If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that ye were our countrymen.” ― Samuel Adams
