There are almost as many sets on Facebook as Ebay these days.
My wife uses it a lot she sold all our surplus stuff after our rebuild, tiles, sinks, plumbing accessories, wood as well as some of the baby stuff we no longer need for our grandchildren.
It's free (no fees to seller) I will be offering sets shortly.
I have bought a couple of sets locally and would have bought more but I am trying to reduce the number of sets
Cheers
