Best Of The Web (my personal favorite paid directory) is offering a 20% discount on submissions to their directory and other services for the month of September.
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 $240 for a lifetime listing with this discount) 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 BOTW and get the discount you simply need to find the correct category and use the discount code SINCE94.
You can view their directory and/or submit your site at http://www.botw.org/.
