...have gone down.
In fact, some have plummeted!
I've just sent some BB7s off and they only cost £3 to send first class. Yesterday it would have been £6.20!
My post office lady has a new box . If your packet fits in her box, and it's less than a kg, it's three squid.
And that is market forces at play. Loads of couriers were cheaper than royal mail, I stopped using RM since the hike.
Used them for the first time in ages today £3. That's better. MyHermes will still get the bigger stuff.
