What do you mean by that? Their prices are higher than most, but anyone can purchase from them.

I was told by someone that works there that you have to have a business license to make POs. I didn't push it beyond that and have never tried it myself, so who knows.

IIRC they don't even tell you the total price until after your order is shipped, which may be a deal breaker for some people

The McMaster site doesn't show shipping costs, because they package your items and then get the dimensions and weight. They only ship things very fast, and they charge you what that costs. They are optimizing for fast and correct, not cheap.

If you're concerned, you can call or e-mail them to ask for an estimate. It's worth noting that free shipping is never free -- it's either hidden in the item cost, or some corner is being cut.
