What is something you wasted your money on, then regretted and how much did you waste?

Have you ever bought something, got home, and went WHY DID I DO THAT? (something non-returnable)
What was it, and how much did you waste?
I bought a $40 dollar wig online with bangs (ive never had bangs before)
thinking it would be a nice change... nope, I look like a fem-bot from Austin Powers, or like a 60's model.. bangs and me dont mix, and ofcourse its non-returnatble..

Sometimes, I can have a bad case of buyer's remorse and regret what I bought but luckily to return the item. It's funny that you mentioned about buying a wig and regretting it because yesterday, I just got a wig delivered to my home and excitingly waited days for it to arrived because it looked so cute online. When I finally put in on, it looked horrible and unfortunately my sister had quite a laugh seeing the wig on my head. There goes $46 dollars wasted and yes, it was non refundable. Now I'm pissed and I saw another one on a different website that looked much better and seem more natural looking. Right now, I'm debating about that one because I'm afraid that I might waste my money again.
