This is still a reason why I haven’t bought Plenny Shake lately. The rules have changed a bit now, most outside-of-the-country items above 300 NOK (€30) have gotten cheaper. However, it looks like food-stuffs is still as expensive as before or more. 
If you had registered in the VOEC system then the fees would be lower (about €30): Jimmy Joy and VOEC
You said you’d consider it there. So if not any resellers in Norway, then at least doing the Norwegian VAT-calculation on Jimmy-Joy’s side would make it a bit cheaper for us 
Edit: Having read into VOEC, sadly Jimmy Joy cannot register, since you sell foodstuffs which is not handled 
So the easy way out is sadly not available.
