McMaster is a great resource but they sure are proud of their inventory. I use them as supplier of last resort on most purchases. Recently I needed a bulk of closed cell foam. Their price was 400% higher than Foam Factory.

One of our club members is rebuilding his trailer and reported that McMaster's felt was substantially higher than what he eventually bought from an internet search. That being said, they do have anything and everything a tinkerer could need.
