Credit Card processing, Shipping and Pricing. When you place an order you will receive an email confirmation that your order was received. Your credit card will be authorized for the amount of the product and estimated shipping. Your credit card is not charged until your order is shipping. Please note: if you use a Debit card the funds may not be available in your account for approximately 7 days due to being frozen by your bank. Shipping cost will be calculated when your order is prepared for shipment. We will use the most economical and expedient means possible to ship your order based on your shipping address and delivery time requirements. Priority mail is very fast and reasonably priced for smaller items or using Flat Rate Boxes for heavier items. Larger packages, such as cowlings, and very heavy items are shipped via FedEx Ground or UPS. Express mail is generally the least expensive option for overnight service. Some locations in the US are not guaranteed so we will use FedEx or UPS, which will be more expensive but guaranteed. Prices are subject to change without notice.
