You can always use your personal mailbox: Just write letters, attach items to store, and Pelly can save up to 180 extra letter slots for you.
x u x That is true but that's a little bit too much of a hassle since I'll forget where I put what, haha.
I ended up filling my museum rooms and all other storage. I ended up selling everything I knew I truly wasn't ever going to use.
I would try to maybe sell the ordables and just keep the important un ordables stored. I need to clear out mine though.
