If you're sending it to Gamo for repairs, they want $10 for shipping and handling to return it, plus whatever it costs to get it to them in the first place. You would need to check with UPS/FedEx/USPS to see what the cost is from you to Florida. If you decide to send it to CharlieDaTuna, same deal. I sent mine from Washington State to Charlie, UPS 3 day, cost me $36. Bear in mind, Gamo has a 4 to 6 WEEK turnaround time on repairs. Even though the busted main spring in my CFX was under warranty, I went ahead and sent it to Bob. Turn around time, 1 week and 1 day, it'll be here tomorrow. That's almost worth the $150 all by itself. Actually $180, since I included extra for expedited return shipping. I feel like a kid at Christmas tonight, can hardly wait for my gun to get here tomorrow. By all accounts, a Tuna tune defies description, guess tomorrow will tell. Good luck, and hope this helps.
