Taimur,
I get it at a local speed shop, K&G in Broomall, PA 610-359-1616. It's on Rt.3 about 1/4mi west of I-476 ...not exactly convenient for L.I. I just called to make sure they didn't sneak in a price increase on me, and in fact as of today they are still selling VP C16 for $11/gal. They have pretty much any grade fuel from 105 unleaded to methanol and nitromethane.
As far as shipping, have you tried to get it directly from VP? If K&G can sell it for $11, VP must sell it for quite a bit less. If you can't buy direct from VP, I'm sure K&G would buy a drum just for you, not sure about shipping it thoug, call them; but you could pick it up I'm sure, I've seen guys take whole drums away. Too bad you're not closer, I'd split a drum with you. Not that it's practical for you, but the guys at K&G also told me that they buy drums of fuel and store it on site for specific customers "private stash" ...once I went to get C16 and they were "out" but had two 55gal drums of it that belonged to somebody else.
PS - alternative idea: together we can order up a 55gal drum for our private stash and have them store it at K&G; you can drive down and pick up half or whatever you can carry back or use it as you need it ...do you have any metal drums to take half of it away? In fact, I think VP sells it in smaller than 55gal drums, maybe you could just buy a smaller drum of it and I'd meet you near Atco to deliver it. Hey, I'm going mental now with streaming video flashbacks ...they sell it at Atco, look on their website under "speedshop and fuel" and call to see how much. Maybe they do that at Englishtown too.
