Anybody who’s ever ordered anything substantial from B&H will likely, at some point, receive a printed catalogue. This is essentially an inch thick (or bigger) 300+ page book featuring every product in B&H’s inventory. I’ve received them myself in the past. It started after ordering my first “Pro” lens. I didn’t ask for them, and after receiving the second I wanted no more.
Having to throw them out is a terrible waste, and not throwing them out when a new one arrives is simply taking up space on the shelf that could be otherwise better used. There is an easy way to stop the printed catalogues from showing up regularly on your doorstep, though. All you need do is simply fill in this form on the B&H website.
