had 3 consignments from WGC Shop since Brexit and 2 consignments from Rainbow8. Both rainbow8 consignments came through without issues. 2 of the 3 WGC consignments came through as they should have. The 3rd one I got hit with a handling charge - which I don't think is anything to do with WGCshop, its more to do with DPD and who they choose to handle the customs side of things.
It's been slower than pre-brexit, but that's public knowledge, so don't be too surprised.
