Offers before next Quest arrives

winterthur

What are the offers (apart from Energy bundles) generally made available before the next quest turns up?

Managed to save 1k units. Will try to add 500 more in case Awakening Gem comes up (will it?).

They only just offered a 4* awakening gem at a hefty £99/$99; I'd be amazed to see another one anytime soon, and even then not for units (or certainly not for less than 4K or more).
