I think that they're extremely useful. This really isn't spam! lol
First off, there's
swagbucks
It seems pretty legit. Apparently, you can use their search engine instead of google (although it's not as good, so use it for simpler searches) and you earn what are called "swag bucks". The more often you search, the better chance you have of randomly earning them.
You can redeem these for prizes, such as gift cards, cds, books, even an xbox and iphone. I've done my research and so far, there hasn't been any word on whether it's a complete scam or not. Many people swear by it and there are even videos on youtube proclaiming its authenticity, where people are opening their prizes.
Examples:
36 SB - classic VHS or Vintage Records
45 SB - Amazon.com $5 gift card
50 SB - Starbucks $5 gift card
25 SB - various limited edition music prints
10 SB+ - various sports cards
3800 SB - iphone
4100 SB - Xbox360 premium bundle
seems pretty cool, and it's free. I don't think it gets any better than that.

Also,
there's redflagdeals.com
They have tons of deals posted on a daily basis, from in store sales to online printable coupons + FREEBIES! For example, there are $5 baseball tickets to see Bluejays games on certain Tuesdays (April 7, 23 & June 2, 23 i believe). I'm going to the game on April 7
