If you are using the Royal Mail Packet Post system be aware, that the pricing changes that are planned for April 2nd will affect you as they are putting a minimum rate on packets.
Royal Mail and their new postal charges coming out on April 2nd are not in favour of businesses posting packets. They want to charge a minimum rate for businesses on all packages up to 750g.
However the standard rate prices for the general public and larger companies for packets 1-100g, 101-250g, 251-500g and 500-750g are still in place.
They are not offering a fair playing field and small businesses that use their packetpost service need to be made aware.
