Better Together Admin allows you to easily create “buy one, get one” discounts for your OpenCart based store. And it works right through your regular admin panel; no need to edit code to create the discounts. Here’s a video:
I have released Discount Chooser for OpenCart (a port of the Discount Chooser / Free Gift Chooser algorithm from Zen Cart). I’m excited about this software and hope it really helps OpenCart store operators.
Discount Chooser goes beyond the standard BOGO discounts to permit the creation of much broader offers. For example, you can create “Buy 2, get 1”, “Buy 3 get 1,” or “Buy some number, get a choice of some number.”
If you open the stacked three dots menu in your browser (to the right of the address bar) and open “More Tools -> Developer Tools”, then press the stacked three dot menu on that dialog, you’ll see a checkbox under Network with the label “Disable cache (while DevTools is open)”. Check this, and you’ll always be using the freshest copies of your css and js files.
