[Remember Last December? Plan Ahead NOW!]

True. What I was saying is to look at market that will actually do business. There are enough people who are working in December and are NOT on holiday. Focus on those. Also, expand your geographies - target countries like Thailand, India, where Christmas is not a big event. 

[Remember Last December? Plan Ahead NOW!]

During December I focus on clients who own E-Commerce (Shopify/Amaozn/eBay/own site) give them Pinterest promotions, etc.

Basically shift the market to people who provide shopping or shopping experience (i.e. recommendations). This can boost your sales up!
