I've found the best buy to be Douglas & Sturgess out of San Francisco.
You're talking best quality with Johnson & Johnson namebrand. The best buy
is the long flat sheets of the stuff. You can also finagle the price if
you're savvy enough. Don't know what it is now but a couple of years back I
bought a huge batch of the stuff and it came in long boxes and each box was
$11. Sure beat the going rate at the med. supply places which were going for
$25-$38 a box of a doz. small rolls. I imagine the price has gone up since
then. Check out their on-line catalog and see what the price is now.
