It would be good if Ebays legal team read the act as a number of sellers are not adhering to our UK tradings laws.
It would be wise to read section 2 of eBay's user agreement. eBay makes it clear that they do not review listings or their content, which are the entire responsibility of the seller.
There is no point in referring eBay to your consumer rights. These are between you and the seller, where they apply and if they are even enforceable. Buying from unknown sellers on eBay is not like buying from the shops. eBay warns buyers that "they do not guarantee the existence, quality, safety or legality of items advertised, or the truth or accuracy of descriptions".
Would you buy from a shop that stated this? Every buyer on eBay has accepted these risks, but how many realise this? eBay is a jungle.
