Sources for 3M Scotchbrite/Roloc/etc. products?

[Mike Lee - Team Banana Racing <mikel@ichips.intel.com>]

Hi folks,

Any suggestions as to mail order sources for 3M Scotchbrite/Roloc/etc. products?

Finally got my shed up, attic insulated, and walkway done, so moved a bunch of
cra^H^H^H stuff into alternate storage spots, so I finally have room to work
on the car.  I went to the local paint supply place to get some roloc mount
Scotchbrite pads, and was quoted $15....each...  Now, I seem to recall they
were more in the neighborhood of around $3; is inflation that rampant these 
days?

Any sources for this stuff as well as generally autobody supplies would be
appreciated.

Thanks,
Mike
