The Sell Your Item form which many eBayers have grown to love over the years is to be discontinued in May this year. It’s replacement the New Sell Your Item form is already used for over 60% of new listings on the site. eBay say listings created with the new form are completed 20% faster than with the old. The downside is that it holds more information on one page, and so people with slow bandwidth connections can struggle, although it should still be quicker to work with.
Personally I’d recommend anyone listing in quantity to use TurboLister or similar bulk listing tools like Spoonfeeder. Although they have occasional problems in the main listing is quicker, repeat listing from saved templates takes a couple of seconds, and with back ups you can keep copies of old listings forever!
