I got one super deal. 99 cents bought me 300 rubies, 1 chest of CIs and 1 chest of Tools. I've never seen it again.

As for deals that use rubies I usually check out how much the items cost in rubies at the "store" then compare. Sometimes there are actual deals on food for extra energy and chests with tools. I've gotten several offers that were 90% off and they actually were. Tools and extra energy will be usefull at first until you start making collections that give them out as rewards.
