Click on buy. Then it will prompt you to log in. Once you've done that, you'll be on a page where you complete the purchase. You will be able to see the discount applied if there is one being applied. As long as you don't actually click to complete the purchase, it wont actually use the credit (or the $2 that got from the new code) so you can just close out the tab once you have your answer.

I think the single game should apply $6 for having bought a Paradox pack. The 4-pack should apply $18. Together they amount to $24 in credit, and if you got two packs it should have brought it up to $48. Which is what you reported. So i think that this is probably your answer.
