A running record of Marketing ideas, including marketing sites that have had a positive impact on your sales.
Riffle - $22.50 - $25 (if used with TNBW discount code)
Thunderclap - Free (set up a campaign, get people to support you - Thunderclap it facebook group helps)
BookTweeters - $51 for 3 days of tweets (have other packages) gave a small boost
Booktweeter (not to be confused with booktweeters) - $5 package of 100 tweets spread out - waste of money
Facebook (paid ads per click) - you set the length of campaign and the daily or lifetime budget - Not worth it
The Fussy Librarian ($14) - Not worth it for a Sunday promo. Might try a different day of the week.
