Shipping charge change notification

We have just received a shock when we were going to the USPS website to ship a few of our orders.  We are now not allowed to ship the manner we have been accustom to which forces us to increase our flat shipping cost from $9.85 to a overwhelming $17 plus.  USPS is still the least expensive means of shipping.  We  have been able to bring it down to a $14 average but we will be looking to alternative shipping.  We are truly sorry for the massive increase.
