If it’s Saturday, and it’s between 2 and 4 p.m., well there must be a Shop N Drop going on! Bring your stuff to 3815 Mt. Vernon Ave. If you can’t make it down, drop us a line, and we’ll send a white-gloved removal crew to your house instead. One of this week’s finds: This supersnappy travel case. Wanna buy it? Can you donate something cooler?
