Some bigger orders require multiple packages and the final weight of the package cannot be determined until the order is fully prepared. In that case, the order total which the customer sees is only an approximation. Some jarred goods may also require special packages. Due to these special circumstances, only an estimated shipping charge can be calculated to create an approximate order total. If the Final Total is different from what you originally saw, we will inform you of the final total charges via email or a phone call. Only when you accept that new amount, we will charge your credit or debit card and ship the package. If you prepay for the order using Paypal, upon the completion of the package and final order charges, we will either return the difference or ask you to pay it, depending on the case.The invoice/receipt with the final total is always attached to the package for your records and sent by email.
