If you’ve walked down West 18th Street (between 5th and 6th Avenues), you might have noticed a new form of “window shopping” from Kate Spade. The company teamed up with eBay to bring the coolest shopping experience to the street. Each window contains 30 pieces from the Saturday collection as well as an enormous touchscreen that you can use to shop for the pieces. After you’ve selected your items, you’ll receive a text message where you’ll respond with where and when you’d like the pieces delivered. Delivery can be in as little as an hour. You don’t have to take your credit card out on the street because the payment occurs when the messenger arrives at your door. Check it out!
