@shunter some of us were told by Kobo cust serv that the format would be programmed back onto the site not long after the new look site was introduced last August(?).
We've been dealing with the how to identify an Epub since then.
You'll find everything you need to know down in the Kobo Devices sub-forum where there are many many threads on it. (I've got one there from last August(?) Myself).
We all live in hope that the next Maintenance update will include this vital info. So far we've hoped in vain.
Edit
I'm not intending that my post come across as negative .... your information will have no doubt helped newer members to this thread understand a bit more about the Kobo purchasing process.
