I've written about Darren Rowse and his 31 Days to Build a Better Blog course before. I think very highly of Darren, his book, and his course.
This month, Darren has been offering both the 31 DBBB course/ebook AND his new(er) book Copywriting Scorecard for Bloggers for 25% off. But you MUST ACT NOW to get the discount! This is only for the month of November (which, by the way, ends tomorrow). The discount code is November25 (think 25% off for November). Enter this code when prompted at checkout to get your discount.
Both ebooks are regularly $19.95, but with the discount, they are $14.95 apiece. I recommend you get both – especially since they are not usually on sale!
