I checked the PO figures and they were correct.. as a matter affect I always say it is 1 cm over the actual size and add 100gms to make sure that I do not get caught for under-postage.

The problem is on the AP computer.. they have a set form they fill and there is no way to alter the end cost to match the C/S cost.

That is why I going after click and send. for false and incorrect pricing. 

If they quote a price the post office should honour it.
