Information: Scoop St., Groupon, and other "group discount buying sites."

ReadWriteWeb has an interesting article today about group discount buying sites like Scoop St. and Groupon. Like Woot, the site features exactly one new deal each day - but a certain minimum number of people must agree to buy for the deal to be activated. (If they don't get enough people, the deal simply expires and nobody is charged.)

Today, for example, the Seattle Groupon deal is a $30 gift certificate to Galerias Gourmet Mexican Restaurant for $15. Not bad! While Scoop St. is New York-based, there are others out there that cater to various markets. Here's my referral link in case you want to join Groupon (full disclosure: I get $10 if you join and order a Groupon). I should say that I myself just joined, so I can't personally vouch for their deals, but it sounds intriguing and legit.

Ever tried one of these sites? Tell us about it in the comments!

Get clean with $30 worth of free coupons.

Cleaning my house is not a great interest of mine, so I don't think I'll be using this one personally, but if you like to not wallow in filth, you may want to sign up for this coupon book with $30 of coupons from the likes of Febreeze, Swiffer, Mr. Clean, Cascade, Dawn, and more. Then you can come clean my house to express your gratitude.

Better than free: Wise Bread's money-saving book is $-5!

What's better than free? Getting PAID for free stuff. Wise Bread has a new book out, "10,001 Ways to Live Large on a Small Budget," and they want you to have it so bad that they'll pay you $15 for a $10 book*! Furthermore, they're giving away 5 Flip Minos cameras for those who participate today.

How this works is, you order the book today and forward your Amazon receipt to the email account provided, and they'll put the credit into your Ebates account when you sign up as a new member. It kinda blows that existing Ebates members (like me) aren't eligible for the $15 promotion**, but Ebates is a good online-shopping-rebate site, so if you don't already belong, you should totes sign up for this offer.

**I actually emailed them about it, because I was annoyed that the homepage claims "everyone" can get the refund when that's not really the case. Updates to follow if they reply today.
