I have been on Joe's email list for quite some time. The link to buy tickets for the fall sale, from the official JB mailing list email, directs to a livenation site for purchasing. Sorry, this forum does not allow posting links, and I can only add hosted images not attachments to the forum post. If you get the email, it's as simple as clicking. It is titled 2022 Fall Tour Pre-Sale - Get the Best Seats Now!
This makes one believe there IS a JB Fan Club. I saw this on previous ticket sales when tour dates were announced as well, like the spring tour. It just seems crazy that people say there isn't one, yet the official link to the so-called official ticket sales site says there is. Please note this IS clicking the link directly from Joe's email to buy tickets now, not going off to some obscure Joe's Fans facebook site or whatever.
This image asking for a pre-sale code and indicating the existence of a JB Fan Club comes right up on the page and you cannot proceed during the first 48 hours if you do not have this code. Either someone is just calling it a JB Fan Club and it's really not, or there is actually one, and seems like nobody has any info about it (?).
