I live in NJ, and I can get cheaper ammo shipped to my door from Palmetto Armory than from the shop whose link you posted.
With the exception of having to purchase pistols in NJ, because of the dumb federal laws, whenever I buy ammo, or accessories, I usually try to do it online, or out of state. I absolutely refuse to spend my money to pay taxes on firearms products in NJ, because I know that the money spent will probably go to the brain-dead morons that pass laws to further curtail my 2nd amendment rights. Why I need to show an FID to purchase pistol ammo is completely bogus. It is none of the State’s business, period. NJ’s gov’t is so brazenly anti 2nd amendment, that the last attorney general had the gall to send out a form letter to FFL’s and firearms dealers in PA to create a log of NJ residents that purchased products from them. Well, the long and short of it is that the vast majority of them told AG Anne Milgram to go screw a lamppost. The sad thing is, is that if you eliminated all of the socialist toilet cities of NJ, we’d be a solid conservative state. It’s just one of those situations where because the cities are so populated with socialist, welfare-entitlement collecting morons, that the rest of the normal populace has to suffer. It’s no wonder that the state’s population is shrinking.
