i will use USPS if someone wants, but its always a risk on their end because USPS doesnt make the best guarantees...usps priority being 2-3 days, and even express is sometimes 1-2 days...i'm pretty sure you can check on their website and it'll give you time committments....i prefer UPS overnight, 2nd day or ground if they are close enough...ground is always significantly cheaper that overnight and sometimes can get there the same time...should be able to see on ups.com as well.
