I sent out two things via exrpess mail...and they were promised next day delivery. ONe at noon, and the other at 3 pm.
The one that was to be deliverd at noon was delieverd at 1pm that very day.
The one that was to be delivered at 3 pm was delivered the next day at 9 am.
I got my postage money back, and meet the deadlines i had to meet....so technically, i just kicked ass.
check delivery times bc if they mess up, you too can have this feeling.
