Here is a link.  They are hiding it and trying to force the horrible online service.  2 out of 3 calls to the sales number will get people lying that they don't sell it anymore.  The company will probably be out of business in 5 years due to how poorly they managed this while simultaneously tanking their tech support.  Have you ever given so much money to a company that hates you so much?  It's baffling how they think this is going to work out in the long term.

Be aware that they are intentionally bugging the desktop version now - the worse it works, the more likely you will be to settle for online.  Planned obsolescence from a company that truly hates its customers.  

I suggest avoiding using that link to purchase a new license. Many of our clients did not receive their license codes and it was difficult to contact Support. In the end, they blamed our clients who used the link and they had to ask for a refund. Better yet contact their sales team or purchase a new license through a reputable partner.

Is there anywhere I can buy a 2023 or 2024 boxed copy of Quickbooks Premiere Edition?

They no longer offer a retail edition (boxed edition). You can purchase a new license via partner and get $100 cashback.

Which partner?
