eBay buyer protection policy is quite clear about an item that is different from the one put up for sale. The example they give is receiving a copper ornament instead of a gold one.
What I'd like to know is their policy about an item that is the correct type, model, etc., but has a significant defect that is not mentioned in the description. E.g., a camera that does not funtion properly, has a cracked lens, etc. Or a computer hardware that has a major defect.
I'd also like to know if the policy covers second-hand items. Please note that I'm not facing any such problem at present. But the information will be useful to many members for future reference.
