Just a few words to add some more data on ordering from McMaster.
I placed my first order yesterday at about 5:20 PM, specifying ground shipment. They have several options but they don't price them in advance - odd. Anyhow I picked ground and much to my surprise the package arrived at my door via Purolator today at 12:15PM. Either they subbed delivery out to the Wood brothers or it came by air! That beats Digikey's 2 - 3 day "overnight" shipping! Oh, I'm in Nova Scotia so not exactly centrally located.
The other tidbit was I filled in my company name on the order which seems to have met their commercial customer requirement.
All of the tax & border bureaucracy was included in the transaction so no dinger fees etc.
That definitely opens up more options for parts ordering although they're not the lowest cost option. That said, they also don't sell cheap goods either.
