I believe most have sent it usps express. about $18 - $20 next day shipping.
i personally sent it usps priority $5 - $6 with tracking, but thats because i live a few hours away, i sent it to the p.o. box but would suggest you send it to the direct address, if using either method. it'll be quicker, because who knows when they decide to check their p.o. box mail

either way make sure and get tracking.. & signature if you want to feel better about it
