Is there a time limit for getting the Mew Z-Crystal?

Question

I wasn't planning on getting PokeBank just yet. But I'm worried when I do order it, it would be too late to get the Z-Crystal.

Answer 1

January 25th 2017 - October 2nd 2017

According to Serebii you have until the 2nd of October to get the Mewnium Z. You can only get one Mewnium Z.
