For Eidolons, yes. Eidolon Store is coming up in... uh, I forget and am too lazy to check, but let's say six months.

You can then sell your dupe event SSR Eidolons and buy raid-event SSR Eidolons, 4:1 ratio. It was something like 150 points per sold event SSR (per limit break) and 600 points per bought raid-event SSR. I forget. Too lazy to check. Either way, keep your extras in your inventory. You can also sell SRs for a pittance of an amount, I'm piling up Disaster SRs in 3-star piles (4-star costs 10k Gems, no thanks).

The Eidolon Store also sells one (1) copy of Kaiser Dragoons, for a measly price of 10 000 points. They don't restock, but those Kaisers are pretty good as secondary Eidolons now that they've been buffed, even at 0-stars.
