Thank you all for your advice. When in Sevilla, I had asked the concierge at our hotel her recommendations for finding Iberico Jamon. She recommended Baco. Baco has three locations in Sevilla. It had the Sanchez Romero Cinco Jotas for 72 euros per kilo. They hand sliced and vacuum packed the order. During our travels through Andalusia, I was unable to find any other vendor with the the Cinco Jotas until I landed in Madrid and had the time to stop at Cortes Ingles. The same jamon was being sold for approximately twice that at Baco. I had no problems shipping to the US, although I did not declare it in the customs paperwork. The jamon is delicious!!!
