Prefer: 80 customers at $12, which is approximately revenue neutral, but increases your effective ROI / hourly wage... AND you keep the high quality, word-of-mouth advertising.
Basically, you'd prefer to have people walking around with _your_ printed and bound product with nice QR code on the back rather than some hackintosh, ink-jet + scissors on 19lb copy paper and saying: "i PaId moNeY FoR ThiS!!" ;-)
...as I'm in the "home printing and binding biz" (gbc-proclick, hand/kettle stitch, carl rolling paper slicer, hp-laserjet, all for personal/hobby use)... What's the equipment you had to end up getting? I'm sorely tempted to chase a (manual) hydraulic paper cutter, but absolutely can't justify the cost / space. Are you still on color laser or are you doing something else for printing? Jigs for slicing? What's the story?
