If you are thrifty, then you can save money and at times enjoy the odd luxury, even champagne for a celebration. However, buying champagne needs a little knowledge, you need to still be able to distinguish a good champagne from a cheap champagne. It pays to learn a little about the goods you’re buying and how they are made. For a celebration, I wouldn’t choose a very dry champagne, for example, because it probably wouldn’t be to everyone’s taste. In fact, to save money, I would probably serve champagne cocktails.
