SPF means that someone has spoken for the item with the intention to buy it, and the seller is waiting to receive the funds, either through paypal or EMT or in person. The seller lists it as SPF so that others know it's no longer available. The item is considered sold pending payment. So when you see SPF, consider the item sold.
