Ok, you got me. That isn’t really accurate. You can save money by buying in bulk – if you do it right. But most of the time, households are better off just managing their cash flows.
First off, yes you do get a lower price (per unit, that is) by buying in bulk. But it’s not that straight-forward.
And good personal finance decisions often can be analogous to what a responsible company would do in similar situations. Taking stock of your personal net worth is pretty much a company’s balance sheet. And assessing your cashflow is like a company’s income statement.
And since companies buy in large quantities, it makes sense that we should do so if we can, right?
