Most expensive item you won’t use

What’s the most expensive thing you’ve bought, NP or NC, that you won’t really ever use?

I recently spent about 1.2 mil on a Bat Boy in the TP. I failed to roll him during the last weekly quest prize pool. I don’t have a pet that I want to attach him to or a gallery I want to put him in, I’ve just been weirdly fascinated with Bat Boy from the tabloids since I was a kid and I wanted to have him in my SDB.

Anyone else have a one-off favorite expensive item?
