My wife and I dismantle old pallets and build tables and such from the boards. We know at least one place that still puts their pallets out back with a Free sign, and most of those pallets and crates are in pretty good condition.
My husband works with supply chain logistics, and he told me that his warehouses are having trouble getting wood pallets. They are having to look at plastic ones, which have been too high on cost in the past, but now, the edge may swing in that direction so that they have what they need to get their jobs done.
