Fair enough, but wouldn't that work only once? I'm assuming (perhaps wrongly) that Amazon has some measures in place to prevent people from endlessly starting free trials.
There are other Prime Gaming listings in this community, and I already pay for Prime for other stuff so for me it's an added bonus, as I get to keep it later even if I unsub later on.
Anyway, I wanted to highlight the availability to those who can grab it before it expires.
