McMaster is like the backend of an auto parts store. You tell the clerk what you need and they might ask if you want the cheap or premium version, then you pay and leave. You don't want to walk the aisles looking at stuff because you've got a dead alternator that needs to be replaced by Monday morning. Shopping at Amazon is like going to a massive department store. They've got everything but they lay out the store in a way that almost forces you to browse. You aren't in a rush because you are just looking at kitchen gadgets and might also be interested in buying a new pillow.
