13. Wine

It’s hardly a revelation when we say that wine by the glass at a restaurant is often insanely overpriced – like “as much as some bottles” overpriced, because it can actually be marked up by 400 percent compared to the price you’d pay if you bought the bottle yourself at a store or from a distributor.

So, when it comes to the vino, save money by buying wine in bulk and then taking it to a restaurant with a BYOB (bring your own bottle) policy. Easy!
