Hi to all

i have a question, is possible create a products with the excess payments? This is my scenary:
- Product "use100", this product cost 1euro month fixed, but if in the order i receive that the costumer have used more that 100 sms i need to apply an increased payment, 0,001 cent for each sms greater of 100
- Product "use200", this product cost 2euro month fixed, but if in the order i receive that the costumer have used more that 200 sms i need to apply an increased payment, 0,001 cent for each sms greater of 200
Ecc..

so i should set the product to define the smsTo (100) and smsExcessCost (0.001) fields, and when i prepare the order, test the limit (eg 100 sms) in base of the product and apply the increased cost.

Is possible do this scenario?

Thanks
