Quote:ClixSense offers a Premium Membership for the cost of $17. This membership is valid for a period of one year from date of purchase. ClixSense also offers a 2 year Premium for $30. 30 days prior to the expiration date of the member's premium status ClixSense will inform the member that it's time to renew. A member may at his own discretion request to renew their upgrade up to 90 days prior to the expiration date of their current premium status. There are no refunds on a Premium upgrade after a period of 21 days from the original Premium purchase. The added benefits of holding a Premium Membership are described on this page and will not get you more offers or tasks, and may not increase the number of ads available. If you are not going to refer others or won't be able to complete the daily checklist on a regular basis, the Premium Membership may not be for you.
