In a normal year, we have about 20 weekends away from home. We only buy bread when on holiday.
My standard batch is four pounds of flour, by hand, which makes either for 'two pound' loaves (which is a month's worth of breakfasts) or 40 rolls (which is two month's worth of lunches for me, MrsC preferring a jacket potato). They all go into the freezer, having cut the loaves in half. I also make bread for our re-enacting displays. I use a sponge method. All the water, all the yeast, about half the flour for one rise, then add the rest of the flour, knead, then leave for a second rise, and finally shape, third rise, cook.
Usual procedure is get the sponge going while sorting breakfast. Go to parkrun. Once home again do stage two. Then we usually end up going shopping. Third stage around or after lunch. Total time spent is under an hour. Elapsed time obviously much longer.
So it is possible to fit bread making into a busy lifestyle and I wouldn't want to go back to buying.
