i want to offer free Shipping for all Orders over € 100,- on purchases using the manual shipping plugin. So far I did not find a solution how to do that...

Any help appreciated

Hi,
The solution will be to :
- Create 2 manual shipping methods through "Hikashop->System->Shipping methods"
- Set different prices
- Use the "Minimum/Maximum price" options.
