Shipping: Rates are estimated and MAY overstate the shipping based on local (especially on books). We will refund any difference that is $1.00 or more over our actual costs. We ship by the most economical means available. Rates are provided to allow you a fast order process, but if you would like to wait on an invoice, leave the cart unpaid and contact us by email or phone and we will invoice you on the actual cost. If you are sure your order will fit in a priority mail box, you can select that option. If unable to ship by selected method, we will contact you.
