Sharper Image Accepting Gift Cards Again, With a Catch

Good news, fans of overpriced ionic massage chairs that refresh your feet, atmosphere and mind simultaneously, Sharper Image is accepting gift cards again! But you have to buy something worth twice as much as the card, and you have to use it all at once. They're not screwing around here. Our advice? Dispose of your invisible Sharper Image monies as fast as you can before it turns into vapor again. [BW via Consumerist]
