I would like to suggest a change of verbage on the Storefront Contact Us Page. I recommend changing the FEEDBACK / QUESTIONS to COMMENTS / QUESTIONS.
I have had a few ebay auction winners navigate through my storefront after checkout (which is wonderful) but they land over on the Contact Us page and leave eBay "feedback" via this message format to me instead of on eBay.
I'm sure I am not the only one this has happened to, and yes, they were "green" eBay users but as a seller I would prefer for this to be a Comment back to me instead of Feedback. Comment just sounds a bit more professional to me and less "jargony".
