In my experience of raiding neighborhood gun stores, going to a gun show or two, and searching online, I've found the online option the best in terms of price and quality if you have the patience to keep checking for availability.
Just a week ago I scored 10 boxes (of 50 each) high quality 9mm factory ball ammo at under $0.40, shipped. .45ACP has been hard(er) to find, though.
