Got the chance to purchase the Zemi's vault for $49.95, with the opportunity to open it every day for 90 days getting 5 gems per day..well i did not miss a day,, got them all. Today was the last one, the only drawback to this was i was always afraid i would miss it, until I saw that it would "wait" for me. Nice little idea. We can always use 5 gems. Don't know if i would do it again though, thanks Zynga .
