[Microbiology] paper discs for disc diffusion

	For years I've purchased the 5mm filter paper discs for doing
disc diffusion antimicrobial assays from S&S in boxes of 1000.  It
appears S&S has been purchased by Whatman, which now sells the same
discs for the same price per box, but their box now contains 100
discs.    I won't pay a 500% price increase if I have to cut my own
discs with a cork borer.   Suggestions for alternate vendors of discs,
please.   Thanks.    Tom McCloud
