Earn $3 Credit From Vudu – Highly YMMV

I was just browsing Vudu and suddenly receive an email with subject line "You’ve earned this $3 Credit".
All I remember doing is:
- Check my Balance & History
- Browse at https://www.vudu.com/content/movies/movieslist
- Hover my mouse cursor to Avengers Endgame and Avengers Infinity War
- Received email for $3 credit
I have also just received the $3 credit today from watching Last Chance to Watch few days ago and this is a separate credit from that.
Hopefully the above steps is what trigger the offer but again this is highly YMMV. Good luck!
