Westernstar,
I sympathize with your frustration, however, it is you that needs to adjust your marketing strategy, methinks. It's a cruel world out there when it comes to on-line selling.
You have aprx. 6 seconds to make enough of an impression to entice a potential buyer to "stay".
A couple of months ago I increased my shipping costs by aprx. 15-20%. Not only did my average selling price not go down, it actually increased!
Then, about a month ago, a competitor "opened shop", basically mimicking my modus operandi (mix of products, quantities per auction, end-times, etc, etc). I finally figured out who was behind this brand new account, someone I had been selling to.
He has the "USA location" advantage, lists about the same amount of items each day, yet it has not affected my sales.
I attribute this to my customer service. My monthly repeat customer rate is aprx. 250% and I believe that is where the difference comes to bear.
What I am trying to say is that you should (must) position yourself with "uniqueness", be it it in product, product combos, service, or "feel" of your auctions - preferable a mix of all of the above.
There is plenty of business to be had on eBay and it's just a matter of finding that little "sweet spot". I genuinely hope that things improve for you.
