Buying Slots 7 & 8 in the Store

[haendas]

Does anyone know what the requirements are for buying LI slots 7 & 8 in the store?

I've completed the epic quests that gave me my first 2 LIs. The store does not have the unlock available for me though. When I click on "Buy Now" on slot 7 of my LI window, it just takes me to a blank page in the store.

Do I need to be a certain level? I'm currently 48. Do I need to have slots 1-6 full before it lets me buy 7 & 8?

This is the next thing I plan to purchase on my character. I need to know what I need to do to be prepared to purchase the unlocks when it goes on sale next.

Thanks very much in advance.

Just a quick follow up to confirm.
I leveled to 50 and the store now offers me the unlocks.
Thanks again for the info, Nakiami.
