But so far nothing related to my question.

im wondering if there is any solution about this, or in what way i can aproach this problem on the documentation, any help would be greatly apreciated, thank you

Is there any solution for offering free shipping vouchers for only one carrier yet?

I offer my customers either economy delivery or express delivery with express being more expensive but quicker for them to get the goods, I want to be able to offer valued customers free economy delivery but if i create a free shipping voucher it lets them choose the express for free and this costs me more money.

The only way I have been able to get around this so far is by issuing a voucher to the same value as the economy delivery costs on my website but if a customer puts in a large order as shipping is calculated by weight they then still have to pay extra shipping charges if its over 25kg for the total order
