Ebay has pretty much outlived its usefulness IMO. There are now far too many Chinese sellers invading incorrect categories with counterfeits & fakes, making it increasingly more difficult to find genuine items at reasonable prices.
Even worse, it has become a scammers paradise with dodgy listings, hijacked accounts, refusal of sellers to accept safe payment methods, and probably the greatest annoyance of all - non-paying bidders!
The sell-through rate is now so poor that listing costs & FVFs are taking a larger proportion of profits than ever before, so eBay becomes rich at the expense of its casual sellers, who are making less profit than ever before.
