My go to and favorite online ammo dealer is TargetSportsUSA.com out of CT. They have very competitive prices. Yet, if you see them on a site like AmmoSeek, their prices will usually not seem that great - that is until you consider they have free shipping on cases of ammo. So if comparing them to other dealers, on the prices of a case of ammo, you need to compare prices with free shipping from them figured into your comparison. That usually makes their price for a case of ammo the best price or darned close to it. They usually ship out fast although now that I am in TX it takes longer for anything from them to get to me than it did when I was in NY but regardless of that, they get the orders out pretty fast. The one or two times I used their customer service, it was excellent as well.
They also have a Prime membership for $95.00 for a year. What that gets you is a discount on all ammo orders, free shipping on all ammo orders (not just on cases of ammo), free shipping on anything else you buy from them like magazines or accessories, and some sort of free gift from them based upon your past orders which is sent to you in the third quarter of your membership (if I understand that right). I joined their Prime membership last month and have already made back just over $60 of the membership cost in savings on discounted ammo and shipping.
