If you live in the USA, VP-OS plotting sheets are indeed cheap. In Edmonton, Canada, there are zero places to buy such plotting sheets. Google Earth put our one-and-only local map store out of business a couple of years ago. I just bought a pad of 50 plotting sheets, and postage to Canada added $30 US to the price. By the time I get done with exchange rates, that is over $1/sheet.
Any uses I can make of PDF files, at less than 1¢ per sheet, start to look pretty attractive.
