Other than here and ebay (which I’d like to avoid..don’t want to use paypal), where is good to sell unwanted stuff (preferably online)

Exchange and Mart I remember [but main business is cars].
I remember a yellow listings paper but now confused as Yell is a directory listing site on the internet.

(oh I guess local paper classifieds / supermarket / newagents but I was more looking for online sites)

thanks

gumtree

retrobike.co.uk

The yellow paper is probably AdTrader which used to be called FreeAds.

thanks, they all look useful

Is Loot still going?

Gumtree seems to take the place in the market it had.

Bicycle stuff?

Try southerndownhill.com, the classifieds section on there is about as big as this one
