Regrettably, once again I have had to increase the total cost due to USPS shipping rate increases. Any price increases in the last five years have been due to USPS shipping cost increases, which is out of my control. If there was a cheaper way to ship, I would use it. However my product price has remained the same for the last five years - no inflation!
