Oh man, I totally feel your pain with the double milk thing! I used to do that constantly until I switched to AnyList and honestly it changed my entire life. I've been doing the big family meal prep for like eight years now and let me tell you, that aisle categorization is a total game changer for staying on budget. I used to wander around and grab random snacks just because I was lost, but now I stick to the list and save at least fifty bucks a week! It syncs instantly between me and my partner so we never accidentally buy the same thing twice. Its literally amazing how much stress it cuts out when you arent sprinting across the store five times. For the budget side, I always check the digital coupons in my store app first then put them in the list. Just a tip, Walmart Wishlist Creator is a life saver for planning big holiday shopping trips without losing track of things.
