Lol - yes, I foolishly assumed that the new standardized shipping templates would be TradeMe finally putting a stop to rural buyers picking urban shipping by only displaying options valid for their chosen delivery address. I didn't realise (but probably should have guessed) they were actually just making things unnecessarily complex and confusing for everybody.

Also switched to the new templates and am also now dealing with rural buyers (understandably) picking 'nationwide' instead of 'nationwide - rural'. Guess I should have checked the forums before switching :)
