Group Buy sites for courses/ebooks ?

[Murl]

hey everyone hope you are doing great!
I did find a few courses (outside bhw ofc) wich i would like to read/buy but they are little expensive.
My question would be, Are there some Websites/Groups where I can find others who also want to buy it and so we can share the price? if so i would be very thankful if you could share those pages with me

Thanks in for every Help

The problem is most of the group buy site I search are scam.
