Google Play Gutschein vs. Ectos/Zkeys

Hello everybody,

looking for Google Play Card with 10€ or 25€ on it.

I will pay 400 Ectos/Zkeys for 10€ Card
or
3 Stacks Ectos/Zkeys for 25€ Card.

Just let me know

so for 20 euro you give 800ecto/zkeys and for 25euro you give 750e/zkeys?
seems legit.

I think he is looking for ''or'' just one of both and not 2x10€.
Correct me when I am wrong.
