£6.81 a book, but I think the euro and dollar sets come out less.  So, setting up book packages...three books would be £20, some of which would come back via profits from sales, so £20 or less for three books...

Plus any random or directed online sales.  Hmmmm....seems too easy...(but so does photocopying--to me--compared to pre-photocopying technologies, so...)

Thanks for the link!
