One Deal a Day Sites

One deal a day sites are springing up all over the internet. Why? Because they're fun! You can find out about a bargain without being overwhelmed by choices. You can check them very quickly once a day. And there's always the chance you'll find just what you were looking for at a great price!
But you'll always need to act fast, because when they sell out, they're gone. Quantities are always limited, and featured items and discounts are only available for one day.

woot! 

The Best and Most Popular

The best of these is unarguably woot!. One of the most popular sites on the internet, woot! features brilliant writing, a popular discussion group, and an amazingly loyal audience. So loyal that when woot! lists their famous "bag of crap", it sells out literally in minutes.

They primarily sell electronics, usually things like computers and peripherals, or sound equipment and accessories, but some cooking- related items too. They've recently featured a lot of toasters.

Items are sold directly from woot.com to the purchasers, and you must be a woot! member to buy anything. All previous feature descriptions remain in their blog and discussion area, though of course not for purchase.

All the writing on their site is extremely entertaining: not only the product descriptions, but also podcasts, their weekly web roundup, and even their FAQs. And they have the only clever Google ad I've ever seen, in years of ad reading.

Yugster 

Electronics

Another favorite - very well done and very popular - one deal a day site is Yugster.com. Well written, well designed, it also features a limited number of one item per day. But there's also a "Second Chance Offer" when the original product is sold out. Yugster ships to the U.S. and Canada, and changes their product at 6:00 a.m. eastern time.

Bits du Jour 

Windows and Mobile Software

Bits du Jour primarily features Windows software, but also occasionally has applications and games for iPods, Palm Handhelds, and Windows Mobile PDAs and Smartphones. Bits du Jour offers instant gratification to bargain-hunters looking for deals on software.

All software is purchased right from each product's own vendor, providing a welcome assurance that copies are legal and current.

MacZot! 

Software for Macintosh

Another popular software site, MacZot!, features software for the Macintosh platform, plus discussions of the featured apps. Their popular MysteryZot features several low-priced (but unnamed until after the feature is complete) programs in one package, and usually sells out.

The software is sold by MacZot, not by the products' individual vendors. Unlike the other sites described here, products that aren't sold out during their feature day remain for sale on the site's discussion page.
