A company called Mayorca has launched a division, Aucmento.com, which is launching two marketing solutions for eBay sellers. Annuncio is a gallery tool designed to allow eBay sellers to increase exposure to their listings by improving the searching and browsing experience. Amplio is an image-viewer capable of enlarging images up to four times. Aucmento.com said the two tools are available on a 30-day trial basis.
