Dang, I must be the lucky one. I live about half way in between Graf's & Midway. I place an order to Midway and drive over to get it. I place an order to Graf's and a friend of mine who runs a courier route just stops and picks it up as he drives by it twice a day. I do shop the online sales and make my choices thereof.
I only buy powder at Graf's as Midway ships their powder from a vendor out of state. Hazmat fee. But I am always on the lookout for deals on a group buy. Pick some "common" powders and buy bulk.
Primers, I look at gun shows, Graf's or Midway when on sale, or group buys.
Cases, I scrounge the local ranges, shoot my spent factory and save the cases, look on Craigslist, post to the reloading sections here on the forum, ask my friends, etc.
Bullets, depends on whether they are lead or jacketed. Lead, I cast my own or buy from Missouri Bullet works. I like their bullets. I have a lot of jacketed bullets bought from decades past that I have been hoarding to some extent. (Got great buys so I bought a lot). Lately, I have buying "seconds" (jacketed rifle & pistol) from Sierra. They are located in Sedalia, MO. About 90 minute drive. They are quality bullets I assure you. Bench rest matches have been won with their "seconds". I took a tour of the their factory on the first buy. Impressive. I am a Master Tool & Die Maker with 35 years of experience. My focus is very fine electronic components both Molding, Dies, and Assembly equipment. Long story short they sell them by the pound. About 30 - 40 % of the retail price.
Find some gun clubs around and start meeting people and talk to them. Talk to some trusted brick & mortar people and see where they get their stuff from. You would be surprised where it takes you.
