As usual The US Postal Service has issued their annual price increases on Jan 22, 2023. In addition the service also eliminated their Regional Rate A and B size boxes and service. As some or you know I was in the habit of charging for regular Priority Mail Flat Rate shipping at the time of checkout and giving refunds when it was possible to use the Regional Rate boxes instead. Unfortunately this will no longer be possible as the Regional Rate has been eliminated. I always make every effort to keep shipping costs down and will continue that practice but some things are beyond my control. I'll be investigating different carriers to see if cost reductions are possible.
