Get Free Packaging

Sure, they're only supposed to be for mailing stuff, but the USPS will send you tons of boxes--and envelopes and labels--for free, with no shipping costs. The biggest ones you can order are only one cubic foot, but they're perfect for organizing smaller stuff. (They've even got shoe boxes so you can keep your footwear collection nice and neat.)

Plus, if you do need to mail stuff, having all sorts of sizes of packaging on hand in the office can be a real time-and-money saver. (via Consumerist)
