I like MidwayUSA, but as others have said, there are cheaper places for ammo. Northwest Loading Supply used to charge a flat fee for shipping me bullets. They got their money's worth out of a USPS flat rate box, that's for sure.
High prices for ammo and shipping is one reason I started reloading. If I cast bullets and buy primers and powder in bulk from sellers at an area IPSC match, I can load for handguns very, very cheaply.
