I pay together but budget separately at this point. It’s not exact. Like I buy dog food at Costco, I pay for it with groceries and just take $30 From my pet category. Same for toilet paper, dish soap, laundry soap, etc. in full disclosure I just started doing this because I want to know what I’m spending on this stuff so it isn’t perfect, but I also don’t want to spend time separating it in the checkout line.
