It is possible to show both regular and extra prices on the Northmill receipt. This can be achieved by setting up to only export regular price Abicart >> Northmill (NMF) and then create extra prices in Northmill.

Because Abicart and Northmill handle prices/price lists differently, only one price is exported: the active price of the product.

If the product has an additional price, it is the active price of the product. If the extra price is exported, it is this price that will appear on the receipt. So not both regular price and additional price

What to do:

1) Set to only export regular prices to Northmill by checking the setting "Always use regular price for exporting items" >> Save.

2) Create the campaign in Northmill by following Northmill's instructions:
