I don't know if its a good idea to invest too much in this company. I've personally used Ebay for auctions but I think its important to keep in mind that Yahoo just opened their own auction site and its FREE...not even a percentage of the sale price. They also have classifieds for FREE. I think beanies are on their way out and that will hurt ebay too.
I've sold many items on eBay and gladly pay the listing fees and commissions to ensure the higher traffic. As far as the comment about beanies being on the way out.... as always, when one collectible falters, there's another there to take it's place. eBay will continue to reap the benefits of this trend.
