At present everyone in each Sate has a flat rate for freight no matter where they live. I have run with this because as a small operator it is the easiest.
With scary freight rates possible, when you place an order I will check the rate to see if I can absorb any cost. If not I will ask for payment of part of the excess before I process your order.
If it goes up by the time I am ready to send your order I will ask you to kick in a bit extra. You will not be under any obligation to make this additional payment.
Hoping you understand the predicament, Regards Alan
