I don't know how I did it, but I managed to use up six hours grocery shopping...and only brought home four bags of food, plus two 10 kg sacs of flour.
Did a survey of flour prices -- one shop charged more than $13 for 10 kg! Given I'm used to paying $8-9, I was shocked. I wasn't the only one loading up on flour. I returned to one shop two hours after I first visited it and it looked as if the hoards descended, leaving only the smaller bags.
Too tired to cook when I got home...got Vietnamese takeaway for supper...mmm....love bubble tea.
