Anyone ever heard of this? I was given one by my optometrist today. It's all black with gold writing. Looks like a credit card with a 12 digit number on the front. The back reads: "The 12 digit discount code on front of card is good for one-time usage of 65% off, up to $1000 retail. Not valid at any retail location, only available on in stock product, not valid on electronics." It expires in 2 weeks.
