WonderLister Online, a premier eBay bulk listing software provides you with many time saving features that you don’t get directly from eBay.
Consignor selling is a feature that lets you sell on eBay on behalf of other people. Since, you are providing your services to others, you may want to charge a fee/commission on such service. WonderLister lets you keep track of which listings and related sales belong to which of your consignor and also lets you define policies (rules) to charge them for your services.

*** This feature is unique to WonderLister Online and is not available on eBay itself ***
