I got mine as a C&C order from my local store a couple of weeks ago for £1.25! They had stock of the black, pink and teal at the time!
I read somewhere (maybe on this site) that the pedestal mat is for under the sink. I tried to find the black set but couldn't find it.
I got the black ones for £1.25, won’t use the pedestal but the bath mats are handy as spares!
Likewise, I was trying to recall if these were 1970s or 1980s. Crikey.
