We do not agree then.  

I think the policys stated purpose is to prevent fee circumvention and to prevent trading outside of ebays "safe environment" is what is most relevant.  I doubt eBay would sanction a buyer for asking a question that is clearly about trading on eBay with a seller, such as if I buy two will you discount post etc etc

I am happy to continue to communicate with buyers - about price, about quantity and about combined post discounts etc etc - all sales occuring within the confines of ebay.
