Mcmaster.com is the best e-commerce site I've ever used
McMaster is great.<p>This article is also completely glossing over another reason to use them: Their shipping is somehow <i>insanely</i> fast.<p>Almost everything is next-day delivery, even for standard shipping. They've somehow got their logistics COMPLETELY nailed. I believe they have their own agreements with USPS/FedEx/etc...<p>McMaster is generally not the cheapest, but they're almost always the fastest and the easiest.<p>Machining/industry runs on McMaster.
