Will the magazine be back in time...????

I spoke to one of the guys in the print room who said he wants to send me a proof I was like no dont do that just email it to me, cuz the mag takes 8 days to print and reach me and it wont be enough time but he's adament he wants to send it to me and he assured me that everything will be done on time, so now I'm just scared everything was starting to go right I dont want it to start going wrong :-(
