Over the years,
way too many people with English and German both not being their first language have chosen „Abholung auf Convention/pickup at convention“ and expected to receive a shipment. Not being fluent in English, they usually try to avoid writing an english email and thus take serveral weeks until they complain. At that point credit card payments can no longer be refunded without additional fees.
At it turns out, there seems to be a french shipping methods „something-something-convention“.
So we have clarified the name to „Abholung auf/Pickup on Furmeet/Convention“.
Sadly only a single name for all languages is possible.
