Product price based on Y = AX + B logic
We have a product which requires a startup fee. Eg. when the amount is 1 price is €100, but when requesting more all following cost €80.
amount = 1 ==> €100
amount = 2 ==> €180
amount = 3 ==> €260
We cant find a way to setup this logic in 1 product, in Odoo 8. So now we use 2 products, 1 for the first run (€100) and 1 for each addition run (€80).
Is there a way / or App which makes it possible to store this price logic in a single product
