Marvel Snap is back on the Galaxy Store - Coupon enjoyers rejoice!

Opened the Galaxy Store and it asked to update the app - after that I was able to download Marvel Snap.

I see there's currently a $4 coupon available; does anyone know when the 90% off coupon is supposed to be available again?

I know they're only good for up to $5 now instead of $10 but still just wanted to know how long I might have to wait to save that extra $1!
