Does ABX Express do deliveries on Saturday? Or are they open? Their site is really not helpful.

Just in case they pull some crap on me requiring me to wait 2 weeks and such (read all the complaint threads), I've already located both their local branch and warehouse. I have a package which is originally sent via UPS but since they don't have a branch here, they pass it on to ABX Express for delivery to Kota Kinabalu. It's urgent.
