Cher might’ve had it right back when she was singing the blues, but it doesn’t always have to be that way. Entrepreneur Joshua Opperman didn’t know what to do with his expensive ring after he and his fianceé broke it off. So he started a new site I Do Now I Don’t.com as a destination for folks wanting to sell a cursed ring, and those who want to buy one at a discount. (Hey, takes all kinds.) The site has also developed as a mixing place for folks to trade tales of woe. But what we like best is that it even has banner ads for —get this—The Knot wedding site. Can you say “Irony”?
