I will admit, I have been struggling with eBay for the last few months. The changes have been so "hot and heavy" and in some cases so wacky, that I stopped teaching and just waited to see how it shook out. MAYBE, with this last move from checks and money orders to PayPal only, it will settle down for a while.
Interestingly, when eBay tried this in Australia, they were taken to court and backed down, temporarily. I understood the concern for protecting buyers from sending cash, and checks/money orders had their own risks, but credit (PayPal) only has created its' own issues. This, combined with no Seller feedback for buyers has made it a tough market for sellers, but after testing other marketplaces for several months, I don't see a better alternative, YET.
I peruse a number of designer discussion boards and I used this analysis recently. One way to look at eBay is similar to designer purses, etc. You could buy a cheaper purse, but you want the quality that comes from the designer. eBay is hands down, offers the best exposure to the market.
We still sell, so we have been listing on two other sites for over two months now, as well as eBay. We average 60-70 sales per month on eBay and have made ONE sale from the other two combined. Their listings may be free until sold, but, we may be getting what I pay for, nothing.
