B-Stock Solutions has launched yet another marketplace. This one is for Waste Management. Yep, that's right, the garbage company. But guess what...not all their inventory is garbage. In fact, they run trade-in programs for consumers to sell back their old devices in addition to doing corporate technology refreshes. This means when some big company wants to upgrade it's entire base of thousands of Dell laptops, Waste Management will take all of the old machines and figure out the best way to dispose of them.
Check out the site as there is a ton of great stuff.
