Freedom Munitions has $5 flat rate shipping thru Sunday the 18th. No coupon code. No limit. Looks like they have all the most common handgun rounds in stock, plus .223, 5.56, and .308 rifle ammo.
I ordered 500 rounds of .45 on Tuesday. They dinged me for $16.00 for shipping, and then it was in "processing" until it shipped TODAY. I would like my $10 back, but don't think it will happen.
They did the last "$5 Shipping" right after I ordered 500 rounds of .223.
