I've always wondered why rich, famous and powerful people get a lot of stuff for free, when they're the ones who need it the least. Well, the rest of us can get a lot of stuff for free, too, if we know where to look. At About.com we've all been working hard to find the best free stuff in the world to share with our readers.

About.com: Free Things to Do lists all the best free things to do around the world: in the U.S., Europe, Asia, Australia and the Caribbean. Check it out as you're planning your summer vacations!

Spa gift certificates are a great gift for a hardworking mom who deserves a little pampering. Many of the Salt Lake area's favorite spas have special offers for Mother's Day to make it a little easier and more affordable to treat mom to a relaxing spa treatment. Some of my favorites include Heaven and Health massage near the Gateway and Zermatt Resort and Spa in Midway.

California Pizza Kitchen, with locations at the Gateway, Fashion Place Mall and University Mall, will celebrate Mother's Day by donating 20 percent of the purchase price of every slice of red velvet cake sold between May 11-13 to the National Charity League.

The National Charity League organizes volunteer opportunities for women and their daughters in grades 7-12, promoting confidence, leadership ability and social awareness while strengthening mother-daughter relationships.  With more than 170 chapters in 19 states, the league provides community service, leadership and cultural experiences to its members. Annually, NCL members provide more than one million hours of community volunteer service.

One of my favorite summer fun programs for families is Kids Bowl Free. Kids can join the program for free and bowl up to two games per day during the summer at six Utah locations: All Star Fun Centers in Sandy, West Jordan and Tooele; Orchard Lanes in North Salt Lake;  Miracle Bowl in Orem; and Sparetime Family Fun Center in Roy.

Free game coupons are delivered weekly by email. Parents can get in on the fun by purchasing a summer pass for $24.95. Shoe passes are also offered at many centers for around $20.

Free bowling is a great way to beat summer boredom and summer heat, without spending a lot of money. Check out these links for more ideas:
