As everyone is well aware prices have been increasing dramatically over the last several months. This includes the cost of shipping. The Post Office has just raised the cost of media mail shipping for the second time this year. As a result we have to increase the minimum for free shipping in the US from $25.00 to $30.00. The shipping charge for packages under the minimum is going from $4.00 to $5.00. We have tried to hold off making any changes but the recent USPS rate increase has made this change necessary. Thank you for your continued business.
