I believe those are in there to let you top up if you're close to something you want. But yeah, uou can't earn more from the standard way to get points, like in this case, opening shards or soulstones.

If you get the pack and the coins are not awarded, Support will get you straightened out.

a distinction: it says you can't be earn them anymore (rather than not being able to collect in that you can't get them from doing shard pulls or stone pulls.

You'd know as a filthy purchaser.

You're a filthy Trunda abuser though.
