Zulily will give members a $15 credit for everyone who clicks through your Pin, joins Zulily and orders.
From the Zulily website:
Only pinables you share using the buttons on zulily count as new member invitations (not those shared via a “Pin It” button downloaded to your browser, or any other method). When you use our buttons, your unique zulily new member referral code is attached to your pin, so we can track new members who join zulily through it, considering it a referral in line with our Invite Friends program.
What do you think of these Pin & Earn strategies, clever or will you unfollow people if you see too much of it?
