How about every store helping customers locate local agencies that would be willing to take used equipment? Shelters, churches, non-profit agencies would have a place to advertise what they need. Customers would be glad to find a place to get rid of their old stuff. And there may even be a tax deduction in it.
Although it does remind me of Dave Barry’s book, Dave Barry In Cyberspace, where he talks about buying a computer and then throwing it in the bin outside the store as you leave – because it’s already obsolete.
