I have MVS (and other stuff) installed and everything works great, except...
Items can have 2 different tax values/zones: 10% and 20% (ex.: books have 10% tax, clothes have 20% tax).
Shipping allways has 20% tax.
If I order an items with 20% tax everything is OK.
If I order an items with 10% tax than the 20% tax from shipping is not added to the total order value.
I guess that since there are no 20% tax items on order, it skips adding the 20% tax from shipping, but I am not sure where/how to force OSC to add this 20% tax from shipping.
Any ideas?
