The best thing about amazon product listing services is it's automation feature which makes my life easier to manage multiple listings in different categories of products for various websites like ebay/amazon etc. It also has an option where we can upload our own logo or design as well but I don't recommend this because uploading your custom designed logos will cost you more money than other similar service providers out there. A tool must have all important features like automatic data entry into inventory management system from feed files generated by amazon product listingservices otherwise its not worth using them at least for now.
