I shop at our local grocery store 2x a month to get essentials as needed. "Essential" to us is anything we utilize the most, which usually boils down to milk, eggs, bread, fresh fruit/veggies. Every 4-6 months or so my spouse and I go to Costco and get items in bulk. Those trips are typically reserved for buying meats that we can freeze long term, along with frozen veggies, and non-perishables.
I always make a shopping list to make a point of not returning any sooner than necessary (but hey, sometimes I forget stuff anyways).
I tend to be the primary cook, but I make a point of making recipes that involve using dry, frozen, or canned ingredients as there isn't a rush to use them since they don't quickly spoil. Any fresh items are used within the 2 week frame between local grocery trips.
I stopped using it when they banned third party apps and I couldn't use Boost anymore. It didn't seem like a huge loss considering how noticeable of a difference and loss of quality the front page had once all that went down. I still used it from time to time for insight on hobby related subjects, but I'm hoping that Lemmy grows enough for me to stop referring to reddit outright. I'm just happy I can support Boost again on here.
