I sold 30 pamphlets that were photo-copied. I photocopied onto pre-printed designs for the cover, covered the outside in clear self adhesive filme and stapled, squashed the spine with heavy weights and trimed with a steel rule and scalpel. But you have to be methodiccal and careful.
copyrighted it by giving 6 to repository libraries (in UK eg Bodleain) having obtained an ISBN (free in UK) and got a few sales by post through the ISBN which was a fillip. Sold 'em at songwriting workshops one of which I ran.
I did it for the experience not the money but I made a small profit.
