So far, no company has even come close to the convenience, selection, web interface, or speed of the almighty McMaster Carr.
But it is interesting to note Amazon is applying their procurement/distribution skillz to the industrial supply market.
AmazonSupply’s web interface is better than some, and in places it does feel inspired by McMaster (fasteners), but they still have a long way to go. The selection feels more like Northern Tool than a big-boy industrial supply like MSC, Grainger, or McM. The free 2-day shipping on orders over $50 is nice, but I usually get McMaster next day as I am so close to a distribution hub. The free 2-day might be nice if you normally have to wait for shipments.
Meh. Check it out. Keep an eye on them. They certainly have the resources to make an amazing supply house. We’ll see if they are serious about it or not.
