Standard shipping is our choice of ground shipping. This may be USPS, UPS, FedEx, or other ground shipper. Priority is our choice of expedited shipping, generally with 3 day arrival from the time the order is shipped. Priority can be USPS Priority Mail, UPS 3-day, FedEx Express or other expedited shipper. If you absolutely require a specific shipper, let us know when you place your order. Due to quirks or errors in programming, shipping costs are not always calculated by the shopping cart correctly. This sometimes results in Standard and Priority shipping being posted at the Standard rate (usually $11.94). If your order is for Priority shipping and it comes up at the lower, incorrect, rate, we will take the loss and expedite your shipping. See also, "Wow! Is the shipping really that much?!!?
