The Related Stores plugin for Clipper WordPress coupon theme lets you suggest similar stores to your visitors on the store and coupon pages in a sidebar widget.
An extra widget gets created that can be placed in the “Store Sidebar” and “Coupon Sidebar” which will show a list of stores related to the current store by category. Each store’s list of related stores gets cached to ensure there are no performance issues.
Note: The widget will only appear if it is placed in the correct widget area (i.e. Store Sidebar and/or Coupon Sidebar) and there is at least one related store to display.
