If I could do so, I would. Unfortunately the space I have is limited, so it's usually a matter of getting what is available of the usual list at the time, even if the price has gone up (unless in specific cases there are alternative choices that I would be happy with, which are on offer on that occasion instead - such as with air freshener), with enough flexibility that if shopping doesn't happen on its usual day, there is still enough there that there wouldn't be an issue of running out of things to eat/drink for a few days more.
In most cases, I choose own-brand products anyway, so it's not as bad as it could be for others in the same position that prefer branded.
