Don’t worry, fuel hasn’t gone up that much. No, this one is about food. For quite some time now, ever since I’ve been doing it, certainly more than a year, our weekly family-of-4 shopping bill at Waitrose has been £100, give or take about £20, depending on how much booze or other exceptional items are on the list. Given all the news about increasing commoditity prices, and food riots, and suchlike, I keep expecting it to head skywards, but it hasn’t. Perhaps Waitrose already has such overheads that they have enough fat to cut.
