Do items retire from the shop? I'm doing some buying after getting my points achievement and there's a book I want/need but I can't find it in there to buy. I even did a page search for the name and nothing. SubetaLodge says there's 89 items in the blue building shop but I counted and I have 88 available items to buy.

You might not be at the right level to see it :)

Actually yes, I think there is one retired book atm. http://subeta.net/news/14162 It retired last spring.

Retired but no rarity change to retired...

Thanks, also, how do you find old news posts like that? Do you just have a good memory?

It's almost impossible to buy everything in the Blue Building and not have an unbelievably high rank there. You would have had to have sat there for days rejecting quests one after the other. I also don't think that anything is invisible to anyone of rank 30 or higher.

Looking at the Shop Search for it, I doubt staff remembers they retired it.

[edit]

When trying to find news posts, I find it's helpful to google what you're looking for.

Like 'retired' + 'blue Building' sometimes I'll find people have posted about the subject, or an official newspost

Yeah I vaguely remembered that something retired so I googled "subeta blue building retirements" and found the info in an old thread which linked to that news post. :)
