It doesn't pay to have plans copied and send 'em through the mail.
Better to get a download, put it on a flash drive and pay the local copy shop $8 to $12 to print it. Getting plans for free is tough, unless the owner works at a place where he can scan, print, and mail at no (the employer's) cost.
I guess some people have a hard time getting their head around paying for a download, but somebody is providing you a service. You still save a lot by cutting out the mailman.
I was a bit miffed by an Ebayer who sold plans on a download-only basis, then had the nerve to add in "shipping & handling."
