what you need to do is start your own web site, promote it through google / froogle (free!), email anyone who's bought from you to let them know about your website, and keep your toe in the water in small amounts on ALL websites.
yes, ebay's been shooting themselves in the foot for years. they've almost completely stripped the brand loyalty, a process that they started 5 or 6 years ago. pretty amazing that they could ruin a (virtual) monopoly without their competitors launching legal battles, but somehow, they did.
also, expect ebay to get some more lawsuits. their "you can only take paypal / propay / credit cards" is in direct conflict with their "we're only a venue!" cover. they've skirted that venue-cover issue for a while now, but this will be the first direct assault on it.
i only wish the people who brought this on - the higher-ups - were still at the company. this is part of a much longer-term strategy which was devised years ago (when they pushed the first online payment service they owned - whose name i forget - that was the one which "eventually" was going to be required on ebay).
as a sidebar- remember when you'd get kicked off ebay for posting ebay's phone numbers, their stated claim was that they didn't have enough support in place to handle phone calls? well, maybe not. anyhow, i've been buying products at amazon and many other places for years, if the price is comparable, because amazon's customer service is amazing. ebay's not the first couple places i go when looking for something.
