I know this is not C&V specific but this is the platform I live on:

I’ve been wondering for a while why in the for sale thread the OP has to set a price. While it makes is clear and easy for the potential buyer it could deterrent a seller to feel out the market.

So what if we can have a separate thread within the ‘for sale’ section to post items with no price? You can even go a step further and let the buyers set the price online by posting the next highest bid. There is no time limit so the seller can wait until he / she gets an offer to its liking but if the seller waits too long the buyer with the highest bid could have lost interest. This is not a new concept and works very well on the Dutch (Ebay owned) auction site Marktplaats.nl.

Just an idea…
