Everyday Cheapskate: Whether you like it or not, you need a good credit score

I enjoy discovering secret information — stuff most people don’t know about. And I love spreading the word. Here’s an example: My supermarket, like most, offers a “rain check” if it runs out of a product that is on sale. This is really great, in my opinion, because my store’s rain checks have no set expiration date.

Here’s another secret: There’s no limit on how many of that item I can get later — at a more convenient time — with my rain check.
