For example, we went to a dinner theater for Valentine's Day and really enjoyed it, but we felt a little reluctant to do it again because we weren't sure it was quite worth the price (about $100 for the two of us, which is definitely at the high end of our usual entertainment costs.) But in the Entertainment Book there's a buy-one-get-one-free coupon for that theater, and that means we'll probably go back-- at half the cost it goes from a probably-not to a great bargain. There's a lot like that-- from eating out to bowling to mini-golf to boat trips on the Potomac, I feel like someone told me, "There's a 50% discount on fun this year! You've paid for it already, now go out and enjoy it!"
So in other words, thanks to the Entertainment Book, I think we'll be spending a little more on entertainment this year, but getting a lot more fun in return. And isn't that what frugality's all about, anyway-- not merely spending as little as possible, but instead getting the most happiness you can out of your money? Merriam-Webster says that frugality is "Middle French, from Latin frugalis virtuous, frugal, from frug-, frux fruit, value; akin to Latin frui to enjoy." I think investing this extra money in fun will be a good value, and I'm looking forward to enjoying it!
