I agree its good idea.. Just giving you otptions if you want to implment this now instead of waiting.
If you don't want it to show in the categories alter this stored procedure. Once you've altered the SP you will need to touch the web.config or recycle the App Pool so you get a new cached version of the categories.
ALTER PROCEDURE [dbo].[Nop_CategoryLoadAll] @ShowHidden bit = 0, @ParentCategoryID int = 0 AS BEGIN SET NOCOUNT ON SELECT * FROM [Nop_Category] WHERE (Published = 1 or @ShowHidden = 1) and Deleted=0 and ParentCategoryID=@ParentCategoryID and Name <> 'HOT OFFERS' order by DisplayOrder END
