We charge actual shipping prices plus a small handling fee to cover packaging and handling. We also rely on the automatic calculation of shipping by our shipping vendors. In some cases, the calculated shipping will be inaccurate. If this should happen and result in a difference of more than $5, we will contact you before shipping your product to verify how you would like to proceed. We will give you the option to either cancel the order with no penalty, pay the additional shipping charges, change the shipping method, or arrange for in-store pickup. We appreciate your understanding should this happen and promise to work to minimize these occurrences as we discover them.
