"He went to Jared!"
In this economy, nothing says "I love you" like giving the woman you love an overpriced piece of jewelry that you could have purchased for a third of the price from a pawn shop, just because you saw some stupid commercials.
Seriously, guys. There's more to jewelry than a high price tag and "man, is that ever shiny." You might as well buy a car because its color matches your favorite shirt. She may have some preferences in that matter, so if you are so out of ideas that you have to go to Shiny McMarkup, make sure she can return it and keep the receipt.
