Somebody on here (George, Harry Strasil or Jim Koepke, I think) made the point in an earlier thread that if you sign up for Enco's e-mail notices/catalogs, you will soon get a free shipping coupon. When you are shipping steel, that can be a big deal. I use a lot of O-1 round, and Enco's prices are extermely hard to beat, especially with free shipping. Enco's service used to be lousy, but since MSC bought them it is actually quite good. On several occasions, I've bought 50 or 60 pounds of O-1 and A-2 (the rounds are often on sale, flats very rarely) and used a free shipping deal. The savings that way are huge, and the steel has always been good. Having said that, if you need it now, McMaster is tough to beat and their regular shipping rates are tougher to beat. I think I'm listed as a "business at a residence"; I don't know if that makes any difference or not, but in my experience, nobody ships cheaper or faster than McMaster.
