A simple header_tag module to let you place a sales overlay on all special on your site. This is a standalone add-on and makes no changes to core files.
That’s it simply copy all files of the into relevant sections and go to admin modules /header tags and install. It can be configured in admin to set,
1) color of badge
2) badge type
3) badge opacity
4) badge animation
You can also make changes to the badge with some further settings.
