Last year I published a post the morning of Cyber Monday titled "Cyber Monday Deals on...[my niche]" and ranked on the first page of Google for that phrase within minutes. (Still sitting at #3 for that phrase this year.)
If you have a site that Google likes (your posts rank in the first 1-5 pages of Google) then find low competition "cyber monday deals on" phrases, create a post for that phrase, and fill it with 5-10 links on deals related to that phrase.
Don't go for the big, hot, competitive niches like "laptops" or "cameras". Go for the less obvious things.
Bring up Google and use Google Suggest to tell you what some of these phrases might be. Start typing "Cyber Monday deals on a..." and Google will give you some ideas where the niche starts with the letter "a". Do the same with the rest of the letters in the alphabet.
You're going to have a hard time getting an idea of search volume for some of those phrases because they're only searched for this time of year but think like a consumer. If you think a reasonable number of people are going to look up that phrase then get a post published.
To get the post indexed in minutes use the Google Fetch tool in Google Webmaster Tools.
