So I am looking to order a watch before i go on vacation which is on Thursday, and if I get the free shipping, it won’t arrive in time. I want to try their Amazon Prime Free Trial which would allow me to get 2 day shipping, but I’m just wondering what’s the catch? After I order it, can i immediately cancel the trial and not be charged their annual fee, or will it automatically charge me for one year? Thanks

Yes
