The PO window is at the back of a stationery/small grocery store. It’s open 9 – 5:30 on weekdays &9:30 to 12:30 on Saturday. The window’s manned by an assortments of people, some more helpful & friendly than others. Each one of the employees has a different way of doing things. Some will take your package in right away & some will make you leave it at the collection window(I personally don’t like this as on crowded days they don’t take in packages as often as they should). Be sure to ask for a receipt or they wont print one. They also sell stationery/mailers/boxes but stuff has to be paid for at the counter near the entrance before you can use it for mailing. This place is not exactly wheelchair accessible as there’s a one step threshold at the entrance. You may need help to get in if you’re wheelchair bound. Also, be sure to have your customs forms etc filled out or they’ll make you wait for a good while.
