More companies should start to follow staples lead and offer return points for packaging and products that reach their end of life.
There’s a local recycling company near me, and anything like that (including monitors) has a $25 surcharge to take it, but they take everything else free of charge. It was great when I did hardware support, because we could just huck most customers’ old gear at them and it got properly handled.
