Attention   buyers April 2024    Royal mail will increase all postal rates  for the third time  in 2023/4.  At the same time the inland  postal service has deteriorated so that next-day delivery cannot be relied on. Many locations are going days without any delivery at all.   I  will continue to  use 2^nd class post which will be substantially cheaper, with hopefully minimal change to delivery times.

Overseas rates have also risen at the same rate.  Multiple buyers over a short period can save by asking for shipping to be combined but it is advisable to hold payment to wait for a combined invoice.
