I am not ordering every week - least of all the same thing every week - just so I can shortcut my order by using "recent orders".
Just keep my overall order-history and let me pull from that. If you have to prune, set some kind of multi-month expiry-horizon (or even better: a one-year horizon).
If I'm ordering fast food for delivery, it's because I'm LAZY (and full of self-loathing, but nevermind that): don't make me have to apply effort just to re-order something a couple months later.
