Link to Amazon page for 1.5/2.5, you can click "Add both to Cart" below. I talked with a representative who confirmed that the $20 credit doesn't go through until after the games have shipped which is annoying. But I'm happy to get both games!

Edit: For example, this:

https://www.amazon.com/Final-Fantasy-XIV-Online-Time/dp/B00O15486W/ref=sr_1_1?s=videogames&ie=UTF8&qid=1494216488&sr=1-1&keywords=final+fantasy+xiv

the seller needs to be amazon, not a 3rd party seller.

A game like this also works:
