Sam's Folders Purchase

[vortalexfan]

Greetings everyone, I just made the move to buy two plastic totes full of Sam's Photofact Folders from someone locally on Facebook Marketplace for $40 and I'm going to go pick them up (and pay for them) tomorrow afternoon, from what I could see in the photos, it looked like the majority of them are still unopened (still stapled together in their folder binding) and are various volumes ranging from the 200s to the 900s possibly?

I think this should round out my existing Sam's Folder lineup that dates to the late 1940s (when they first got started) up to the late 1950s, and should be able to come in handy if I ever need to work on some old radios for people so I don't have to pay $$ for scans on the Sam's Website.

Did I do good pricewise by paying $40 for the folders?
I was kind of guessing on a price because the guy that listed them just said to shoot him an offer and I didn't want to rip the guy off because I know what they are and how valuable they can be to repair guys like us, but I also didn't want to overpay either. I think there was probably at least 150-200 folders in this stash, but not sure.
