Ebay Does Your Listings Their Way

I just completed a successful listing on several non philatelic items. On each I specified 'Economy Mail' which I usually assume to mean send cheapest. My buyers all received notices that the $5 shipping on their lot was for Priority Mail.

I understand their business model is to encourage rapid order fulfillment and shipping but when I specify one method and they raise expectations by telling my buyer to expect their winning in Priority time, it gets very tiresome. Is there some default in the listing program that keeps doing this on my listings? I'd like to avoid it.

Yes there is a seperate section you need to adjust on the listing page that your filling out . It will pick up your previous shipping method .
