Fabulosity comes at a cost.

To be the dazzling, put-together person you are, there’s plenty you pay for: a well-honed wardrobe, membership at the yoga studio, and weekly mani-pedis, to name a few.

But here’s way to keep your mind as sharp as a stiletto heel, without spending a dime:

PaperBackSwap.com.

It’s an online group of over one thousand readers who offer up books they’ve already read (and not just paperbacks), so that others can have them for free.

Sort of like a high-tech book swap. Or an online library with no due dates.

Here’s how it works:

Sign up and list 10 page-turners you’re willing to share. You get two credits ASAP, as a club-warming gift. With your two credits, you can request two free books right away. When a person likes one of your books, you receive an email request for it. Mail the book, paying for the shipping cost (about two bucks, and -- voila! -- you receive another credit.

So pull out all those novels you picked up at airport gift shops, and start feeding your beautiful mind -- for free.
