Christmas shopping (other than groceries)? I don't anymore. I highly recommend it - no stress - the way holidays were
meant to be! It makes Christmas more like the USA's Thanksgiving.
I do like to avoid parking problems, though, any time of year. When I lived in Sydney, I shopped at Neutral Bay where supermarkets were open until midnight. Often, I'd do the shopping after 10pm - that way I'd mostly get a parkng spot right next to the entrance and there'd be no queues anywhere.
