Just to share ...
I've noticed that Fotohub clear their orders for E-6 in the morning shift/earlier part of the day ... so basically, if you manage to send in your undevep film before 11 or so or as long as they're still running the E-6 machine, and do not have overload (which is unlikely), you might get it back in one or two hours as a matter of routine. The 11am timing is not cast in stone as their schedules will vary according to workload, maintenance, trouble-shooting, special orders etc etc etc
If you send in the later part of the afternoon or evening, then your order gets slotted for the next day's devp run.
IF, by chance you're developing anything other than rollfilm, or your film canister kenar dented or you suspect might be susceptible to light leakage etc, be sure to SEAL the carrier or box and MARK it 'OPEN IN DARK ONLY'. Some of the girls have a habit of Auto try to open a carrier or box of exposed film right in front of you.
