Frustrating prices of some items in the marketplace

I know it is a buyer beware world but it gives me the pips to see some used stuff advertised in the marketplace at around the same as new prices.



If anyone was to ask us about the value of something advertised on gum tree or ebay we would call it as we saw it.



In general the prices are quite reasonable, I'm just annoyed that some members are getting poor value.



How do others feel about this?
