I can think of two situations in the last few weeks that could have used something like this. I just switched from Sprint to T-Mobile, so I got rid of some CDMA stuff like an Airave (mini cell tower that plugs into a broadband router). I sold it on eBay and took a hit on free shipping, but there is more than likely at least one other person in my condo complex with Sprint and bad reception who could have bought it and saved both of us on shipping, PayPal, and eBay fees. The other situation was at my new job. The armrest on my office chair broke, so I bought a new chair. Unbeknownst to me, the business downstairs moved out and they left a bunch of equipment behind. It wasn't until a few days ago that the new tenants started moving in, and I saw them hauling away the unwanted office equipment. I asked about it, and they said we could take anything we wanted before it went on the truck. If only the last company had offered before I bought my chair.
