Best Of The Web (our personal favorite paid directory) is offering a 15% off discount on submissions to their directory for the month of May.
Since DMOZ has become all but useless, Best of the Web (the oldest running directory) has become the most valuable and through directory on the web. For the price of a listing (less than $300 for a lifetime listing) it’s higher on our list than even the Yahoo! directory which is, of course, a solid directory as well though a bit overpriced for a lot of people’s needs and budget.
To submit to DMOZ and get the discount you simply need to find the correct category and use the discount code MAYDAY.
You can view their directory and/or submit your site at http://www.botw.org/.
