Hi Susan & all!
I don't know how ethical it is, but this is what I have done with wonderful results for my potentail buyers as well as myself.
I add to my description a phrase such as "Tired or the bidding wars?" Then offer them a link found on my "me" page called "How bad do you want that item?". I request, respectfully, that they let autionsniper know I sent them.
I have received numerous free snipes & even a few thank you's in my email-box. It's nice to share the knowledge & be able to get around eBay's stickler ways.
