Do I have a spending problem?

I'm trying to unlock every item in the game and have been buying basically everything from every shop for as long as I can afford. I wanted to find out how much my inventory is really worth, and I think it's fair to say I was surprised at just how much stuff I have. Somehow I'm still only at 664/1319 items discovered, so I have a long way to go. But I'm confident I'll get there in the end. I obviously didn't sell my stuff to Yori, and I think he's glad that I didn't, cause otherwise the man would be down just over 1.2 million carrots haha.
