Hi, we do promotions "Buy A get B for free" on our BigCommerce store. Such order than lands in Linnworks with a zero value item. We are struggling to find a way how to ship this outside of the UK (export to EU most of the time) because customs do not like zero value items on commercial invoices.
We have tried different shippers but we can't find a way to handle this.
The best one we have found is DHL who automatically changes zero value items on the CI to 0.001 GBP. However, it's not good enough and customs still pick up on it.
How do you approach this challenge? Any information is greatly appreciated. Many thanks in advance.
