I try not to throw away anything someone else might be able to use.
Right now, I have the following:
Flexible pads for safe packing (9 of them, ranging about 2" thick x 6 " wide x 24" long, and 9 of them 2" thick x 8" wide x 19" long). MUST TAKE ALL.
Ice Packs. Put in freezer, freeze, use in coolers instead of buying ice (about 40 of them, roughly 5" x 6"). MUST TAKE ALL.
Planter Pots, plastic (the kind you get when you buy plants) a variety of sizes. MUST TAKE ALL
Assorted scraps of wood and decking pieces. Not a huge amount but would be cheaper than buying pieces at Home Depot or Lowes. Also have an 8' (roughly) length of flexible drain pipe (4"), a similar length of sprinkler pipe (1/2"), and a few (4-5) of those plastic rippled supports for corrugated roofing. A couple of pallets, too. DON'T HAVE TO TAKE ALL BUT WOULD BE APPRECIATED.
