Attention frequent Short North shoppers: Ask your friendly cashier for a Black Card next time you’re out shopping. The Short North Black Card looks like a sleek black credit card but it’s really just cardboard. To “activate” it you have to register your email address at shortnorth.org. Every day through Dec. 23 you will get an email with exclusive Black Card specials. To get the deal, you have to show your Black Card at the store. That’s all it takes to get something like Saturday’s Rowe deal—buy two get one free from the boutique’s sales rack. More than 40 Short North businesses are participating, and the deals aren’t just lame-duck discounts. This is a card worth snagging.
