While this may not offer much to the international community, for those in the US if you have a Pier1 nearby liquidating you might go by and see if they have any of the shelving left. I picked up a few more pieces today. The price today was $2.50 for 2'x4' sheets of 3/4" plywood or wide pine glue ups. The plywood is among the most beautiful I've seen. No voids, no filler, both sides cabinet face grade. You just have to pick through them to find the flat ones. Same with the pine glue ups. Definitely seeing some decent shop cabinets/carts in my future.
