I would save a lot if I would actually eat the food I have in my freezer and cupboards. I wind up throwing away a bunch of expired stuff (when I finally get around to cleaning it out).
But definitely groceries have really gone up. I too used to be able to get my week of groceries with a sixty+ total, but now it is over a hundred, maybe even 120, but, to be fair, since covid and working from home my groceries include a lot of bird seed. Also, pre-covid I actually went into the store so I would see what was on sale and I would stock up on my favorite food when it was on sale, but now I just do the pickup order that they bring out to my car and I don't pay as much attention to sales that way.
