I'm considering dropping a fair bit of money on what is basically a fashion accessory that I couldn't even really wear that often. While I've been hemming and hawing over it for a while now, I think I'm mainly trying to convince myself to just buy it, even though I'd really regret spending that much money if I didn't absolutely love it. The thing is, it's only available for a limited time, and I'm not sure if I'd regret not buying it.
Anyway, it made me think, what's the worst purchase that you've ever made on a whim, ADISC? Or just anything that you bought but really regretted later.
