Movie and $25

I am trying to sell a never-opened Nexus 7 and a potential buyer asked me if the Transformers movie is on the tablet, along with the other extras. (He is U.S. buyer.) I've been looking for an answer to this and am not sure, actually. I found one thread (No 25 dollar credit - Android Forums at AndroidCentral.com) that said that there is an expiration date for the $25. Can anyone confirm/deny? What about the Transformers movie, does that only come after you get the $25 credit? I don't even remember!

 

Thanks!
I did order these from Google but am fairly sure they are not registered to me.
I have sold a couple of tablets in the past few days, so what I did was send a message to a previous buyer asking whether the movie was loaded/showing up.

 

Thanks!
The buyer wrote back to say they didn't get either the movie or the $25 credit. I wrote back to them giving instructions on how to get both, and am waiting to hear if that worked.
