John,
It's all detailed (in the fine print) on our
Subscriptions
page, but I have no problem going over it here. If you are an active subscriber, you can purchase the SocialBundle (JFBC/JLinked) 12-month subscription for $149.99. If your subscription has expired, or you never had one, the price is $160. So, it's $10 off, but that also includes the 12 month discounts, which also bring the price down, as well as the bundle price which brings it down even more over just buying the 6 month subscription or the extensions individually.
When you go to purchase, if you're logged in already, the checkout page will show the discounted price automatically.
Hope that helps,
Alex
