Our shipping software has been recently updated to be calculated by USPS.  We have noticed that on occasion, the calculations may be incorrect.  

We are actively working on correcting any issues.  

In the meantime, please know that we will reimburse for any shipping overage by offering a refund or baking tool of equal value.  

We will notify you in the event miscalculation occurs.  

Here are the current USPS Priority prices

(which includes up to $50 insurance)

Additional insurance cost is calculated with orders over $50
