If you would like to go ahead and make payment via the automatic PayPal link, please feel confident to do so. However, if you have purchased multiple items for a combined shipping discount, please wait ... we will send a separate email invoice with combined shipping options. Shipment is normally made within 24 hours of receipt of payment. An additional shipping confirmation email will be sent at the time of shipment. Thanks. Mike (MFPilot) - M&T Supply Company.
