What’s everyone biggest regret purchase?

I’m sitting here staring at my biggest regret which is Italica. It is just not for me even though at the time I liked it. Costly mistake. I saw internet love for it so I guess I had to have it.

So, it got me thinking, what does everyone else regret purchasing? What do you think has hype that you don’t get? We often talk about favorites but what do you wish you didn’t buy?
