So, recently I was asked what I do about water. Since that is the majority of what we drink since we've been on this $50 budget, we like it to actually taste good. And our top water isn't the best. Fortunately I'm lucky enough to have a refrigerator with a water filter on it so most of our drinking water comes from that. I would suggest a small investment in a water filter system. You could use PUR which is a water pitcher with a filter attached in the lid or they also have a filter that can attach to your tap at the sink.
Another question is do I shop at warehouse stores like Costco or Sam's club. And the answer, with a sad sigh, is no. I used to love to shop at Costco because I could buy a lot at once and not have to get certain things again for months at a time. But, our new budget doesn't allow for mass expenditures at once. I HAVE to stay on $50 a week. Also, these warehouse stores aren't making the big bucks without putting lots of thought behind it. Just because you're buying in bulk doesn't mean you're actually getting the best deal. They are jacking up their prices on other things in the store that seem irresistable. Plus, if you take a good look at what they are selling it's mostly brand name stuff. If you like paying extra for a name, well, then you go girl. But if it's really the item that you want you can usually find the same quality in the generic brand for a fraction of the price. If I do get a small windfall of cash, I would stick to the basics like baking supplies, (Large bags of flour, sugar) toilet paper, meats and veggies. But that would be out of pure convenience because I'm really not saving much money. I'd challenge you to take your little calculator with you next time and actually break it down to see if you're really saving or not. I think you'll be surprised.
