Sounds like a crock of a reason to me, so its the same cost for shipping 20 miles as it is 1000 miles - yeah right!
If you collect/deliver yourself or arrange your own courier will it be $1400 --- hmmm unlikely.
If its been that price for a long time I don't see an issue with being open that costs have risen and need to be reflected in the selling price.
What I don't like is feeling that I am lied to coz they don't have the courage to be honest.
