There are a number of things that I usually buy in quantity, and we started running low on rolled oats (which I generally buy 16-20 lbs of at a time -- some of us eat homemade granola daily). Kid 1 and I made a special trip to where it usually comes from, to find that entire section of the shelving was empty. Fortunately, their website indicates when things are in-stock, so a day or so after it said our store had more, I went back. Turns out they didn't have 4 lb bags, but did have 2 lb bags, so I bought a mere 4 or 5 (so I didn't wipe out 30% of their supply). I'll have to go back while i'm thinking about it.
The asian market where we usually buy some stuff has been re-stocked with rice, so got a 20 lb bag -- it's in the car, hanging out for a few more days, along with a bottle of hoisin sauce, a big bottle of soy sauce, etc. etc.
Then went to Trader Joe's -- I really like our local Trader Joe's! (even though they stopped carrying white whole wheat flour for like $3/5 lb bag)and managed to get almost everything else on the list. Plus some really lovely looking produce, which means we can go a few additional days before I get to start it all again.
For the people wondering why we're buying 5-10 lbs of flour/week, we're baking bread every couple of days, and making desserts about 50% of the time. There are now 4 full-sized people, including young men aged 15 and 19 eating every single meal at home. We're going through a fairly spectacular amount of food, and everyone's being kinda thoughtful since we're not getting much activity.
