Here is another awesome donation plugin that will allow you to connect eBay to your WordPress site. Namely, the Auction Nudge plugin works by automatically displaying your latest eBay information on your site, including eBay listings, profile information, and most recent feedback comments. You can use shortcodes, widgets, or you can do so directly within your theme. Some of the display options include allowing the users to filter your items by category, allowing you to select the number of items you want shown per page, the ability to show multiple pages, as well as a search box that lets visitors search all eBay items by keyword.
In addition, there are some advanced options that let you choose the order in which you want to display your items, select the listing type, show only those items that match a specific keyword query, etc.
