I did, most unusually, write a list this morning (in English) and set off shopping, with the list happily still sitting forgotten on my desk.
Still, I remembered everything except the raisins and they aren't urgent anyway. The flour was bizarre. The 2.5kg bag of all-purpose I usually buy was ¥23, but they had reduced their 1kg bags from ¥13 to ¥4.90. Neither I nor the nearest staff member have any idea why. So, I bought 4kg for ¥19.60 - less than I usually pay for 2.5 kg. I may go back tomorrow for more.
Hua Lu Shui (花露水 huā lù shuǐ - literally 'flower dew') is a Chinese 'toilet water', which is also a very effective mosquito deterrent. Not only that, but should you get bitten it rapidly kills the itchiness. I'm careful never to be without a couple of bottles. There is one on my desk as I type.
