What is the consequence if the price of a step-up card drops?
Example:
new product: 1.000,00
original product: 700,00
step-up costs: 300,00
shipping: 10,00
Total Step-Up costs: 310
New price of the step-up product in e.g. 4 weeks:
new product: 900,00
original product: 700,00
step-up costs: 200,00
shipping: 10,00
Total Step-Up costs: 210
Do I have to pay the 310 or 210 USD?
