Learning marketing

Marketing is not just for self publishing, nowadays publishers want authors to have a marketing plan and online presence. Also, be wary about what self-publishers offer, things like cards and postcards are not as useful as solid guidance and reliability. After the "sale is done" you might not get what you expected, so a little research goes a longways. 
Today I listened to a She Writes self- publishing you-tube, click HERE to view, it is packed with information.
