Just logged in to Click and Send...there is a message on the home page saying BX1 will be limited to 1 kg, BX2 to 3 kg and BX4 to 5 kg. I expect postage to go up every year but I did not see this one coming! Apparently we have 6 weeks grace.
BX4's were the cheapest way for us to post combined lots. Such a shame to lose that service, such a shame that more services haven't been added.
