I think the only issue is this person not realising if you have 36 people buying 1 book and sending it, 36 people are not getting 36 books. They’re all getting one. Though, it could be a ring where you read then send, so you eventually cycle through to all 36. Issue there is reading speed varies so one person will end up a bottleneck but I mean yeah.

Either way, at this point just make a book club or go get friendly with your local librarian (I mean talk with them you perverts) and they can usually suggest books you would like but may not have chosen for yourself.
