A preferential price means you can set up prices differently in your locations where you want to sell a certain product.
In order to set the Preferencial Price, follow the next steps:
After you logged into your Ebriza Account, go to Configuration.
Select the desired product. On the right side of the product, you have the three dot button. Click on that button.
Click on Edit.
You are now on the Product Page, and you can see where you have the Preferential Price option.
When selecting the Preferential Price page, you will also need to select the location and the starting date when you want to have this new price applied.
When done editing, click on Save.
