Thanks, I've decided not to amend my address after your advice on no refunds on shipping!It depends on the courier. I've had to call the courier a few times because I put in a wrong address. There have been a few times where I needed the shipper to call the courier to change it due to the restrictions the shipper put on the package.
It's also accounting... Depending on what agreement the shipper has with the courier, once the package is in the hands of the courier, the shipper's responsibility is done. Any fees paid are just that, the shipper doesn't get a refund on postage just because the rerouted address is closer.
