Orders are shipped on a daily basis using USPS Priority Mail, UPS Ground, and FedEx. Your item will be shipped as soon as reasonably possible, as long as it is in stock. Out of stock items are generally shipped 2-3 days after you place your order, but availability varies, so inquire via email if you want to be reasonably sure of a delivery date.
Returns are handled on a case by case basis, but generally there are no returns unless an item is defective or damaged during shipping. This is especially true of electronic items, unless indicated otherwise in the product description. Email and request an RMA if you want to return something.
