Yeah, we plan our meals for the week and what nights we will have them so that we know exactly what to get at the grocery store and so that nothing spoils or goes to waste while it waits to be cooked. I think it just works better as a system and it also kinda hypes you up if you're looking forward to s specific dish that week. The best time to do it I've found is on a Monday because Sunday is roast day and you should use all that leftover meat (there's only two of us so there's always leftover meat) in the first couple dishes for the following week.
