Does Mumsnet have a local buy/sell page?

[GembobsB]

I've got a natural Mumsnet/Dreams (developed with mums from Mumsnet) mattress to sell. Only 1 mth old but too firm for me and I cant swap it as I've already swapped once. :( .
I thought here would be the best place to sell it as there's loads of reviews and blogs about it on here.... but can't seem to find where the buy/sell page is. I'm sure there used to be one many moons ago.
