My shelter has some budget for training equipment and we sorely need a new tunnel and two pairs of sandbags. I know I can get them for $$$ on certain sites, but do any of you agility folks know of a Facebook marketplace, or website, where I could find a gently used set of equipment? I don't expect this stuff to be cheap, but we don't need brand spanking new gear and would gladly welcome some savings for still-functional stuff.
