What is a membership, and what is a subscription?

A single membership expires after 30 days. On the other hand, a subscription is a membership that is automatically renewed on every expiration date. If you have chosen a subscription, the second month and all subsequent months are discounted, so the subscription is a much cheaper multi-month solution than purchasing a new single membership month after month. So, a subscription is a big advantage because you'll save money, you won't miss any of the recent updates, and you can always cancel your subscription whenever you want. Furthermore, if you remain a member for at least 3 months, you will gain access to the ultra-high resolution pictures!
