Stay away from prepared foods and buy more cheap staples like rice, beans, and potatoes. Shop the meats that are the best price per pound and know the highs and lows of fresh fruits and veggies to get better deals. Beef and fish have been basically unaffordable lately while pork and chicken have been more reasonable.
The prepared foods and snacks are getting ridiculous. A half gallon of cold brew coffee is up to $7. I can make it myself for a fraction of that, but it's more labor for me. A bag of cool ranch doritos was going for $7 a bag... I chose some cheaper chips I don't like as much, but got 2 bags for $4.50. A can of pad-Thai sauce is $12 at my grocery...

I mean, only a little bit of labor. Even with premium grounds, I can't imagine it costing more than 50 cents to make a half gallon. As for labor, just throw it all in a pitcher, give it a quick shake or stir, then leave it in the fridge for a couple of days. Pour it through a standard filter. I use the basket from my regular coffee maker.
Making your own cold brew is one of the most cost-efficient DIY foods out there.
I've been making cold brew with an in-jar filter that is more complicated than it should be but still not hard except for the pre planning for a few days in advance when I'm traveling for work. I'm definitely going to try it the way you describe though.
