I came in around 1:30pm a couple days before Christmas and there was only a very small line. The selection of boxes, envelopes etc was extensive and a friendly customer helped me pick the right box and even lent me his Venture One card so I could get 5% discount and free insurance (getting in the spirit of Christmas I suppose!). The guy at the counter was kind and helpful and suggested Express Post as I had something I wanted to get a signature on delivery.
The box and postage for a small 1kg package all up cost me almost $20 which I personally think is highway robbery but what can you do? My package arrived at the other end about a week later so I am happy!
