While McMaster's Website is the best in biz, bar none, it does pay to
have a printed
version. Bathroom is an ideal place for it - so you have good use
for those otherwise
dull minutes .

Learn a lot by simply flipping through pages. Got mine @ work.

MSCDirect's catalog is much easier to get and I think it is much
larger, just an FYI. Price-wise
they are about the same, have a number of warehouses - I get my stuff
from both McM and MSC
next day with UPS ground. MSC's website is much worse compared to McM's
- search and presentation
of search results is nearly not as good.

I also have Grainger store within 2miles from my home but they don't
sell to GP. Plenty dumb, IMO -
MSC and McM don't have that problem.
