The module allows you to create decreasing prices for your values, so if it is a quantifiable field (catalog product or accessory) or that the field is linked to the quantity of another field, the price will be calculated based on your parameters.
To do this you just need to put a price on your value, to click on the button + below the price and put your parameters there :
amount of reduction, type of discount (Rising , percentage or package*), customer group benefiting, and quantity triggering the reduction.
The package type will keep a fixed price until the next discount if existing.
ex :
of 0 To 20 quantity the customer pays 20€ whatever the quantity if he takes some 2 it’s 20€, if he takes it 15 it’s 20€)
of 21 To 30 quantity the customer pays 25€ whatever the quantity if he takes some 21 it’s 25€, if he takes it 25 it’s 25€)
…
The amount and percentages type are more classic and set the price of each unit
