You can order Monster of the Week:
From
my website for pdf, or print & pdf.
Or from
the Un-Store for pdf, or print & pdf.
You can also buy
Monster of the Week from lulu.com. The base price is the same, but shipping may be cheaper depending on where you are. Note that the lulu edition is thinner (due to lighter paper stock) and the internal print quality isn't quite so nice.
The pdf can also be purchased from
rpgnow which has the advantage of being instantly downloadable.
