I found this great info from Jane in a thread in the "ETSY Success" team discussion section:
Here it is:
"Someone from another team shared this information.
Go to www.etsy.com/promotions, enter code ETSYSTART2013, click Redeem, then log into your (current) Etsy shop and you'll get credit for 20 free listings :)
Looks like you can save them for later too, which is what I'm doing!
Clickity Click!
