Here's the deal. When you send your items into Amazon they first get checked in to one location. At this point they can be bought by customers but are not eligible for PRIME yet. They will be eligible for PRIME once they leave the first location and arrive at their final destination. Example: You ship to St. Louis, Amazon then ships your items to different locations across the US so they can be closer to any customer that may buy them. That way they can guarantee speedy delivery. At that point the PRIME badge will appear on your item.
