I guarantee you it was altered and changed.
I purchased The Sims 4 on the 1st day of the promo.
Didn't receive any codes, contacted amazon yesterday about it and got the absolute worst indian customer service BS ever. Anyway, they were adamant that it was not eligible and kept copy pasting the new T&Cs to me, which is how I found out that they had changed it.
Gave up with that BS, tried contacting amazon again today and apparently they are fully aware of the issue now as the first thing they asked me was the date of purchase. After verifying it, they promptly sent an email with the code.
*One thing to note is that even after they changed the T&Cs making The Sims 4 ineligible, the promotion is still tagged on there for some reason. Very misleading.
You can buy The Sims 4 for $4.99 and it has the code for the Chocobo.
Edit: Never mind, I’m an idiot - very sorry.. Even though the game has it as eligible for this promo, it looks like there still is a minimum of $19.99. So I suppose you’d have to buy games that have this offer available that either equal together $19.99 or just one game for $19.99. I’ll test it to see if it works buying two games with the promo and totaling the required amount.
