And so would you. Those of us who sell love Ebay for only one reason-they've got the traffic! And when I'm looking to buy, Ebay's the first place I go-why? Because they've got the sellers. I don't expect this to change.
For a year, I've sold a guide on the ins and outs of Ebay, including a bookkeeping system-something nobody else has, and Ebay couldn't be expected to bother teaching. Using my techniques, a person can expect to get top dollar for their item without suckering for a lot of Ebay's whistles and bells. There are a lot of people like me, making money teaching things that are expensive to learn in on-line auctioning.
Three years ago, I completely outfitted myself for an elk hunting camping trip-no, I didn't get the rifle there-and ended up paying about 20% of retail.
I am glad Ebay is there, and if you are selling or buying, you will be too, and you won't begrudge them their size or profits, or their survival tactics. If you were in their shoes, you'd do the exact same thing.
