Holyshitballs it doubled the ENTIRE transaction.
Here's the points breakdown:
RZ Credit Card Bonus: 129
Premier 25% Bonus: 32
Reward Zone Credit Card Premier Bonus: 32
And then it doubled that for a total of 644 points.
That's amazing, not only did I not expect to get both premier bonuses (I assumed using a credit card would override the standard 25% silver bonus instead of it giving me both.) but I doubt it would just add on another 129 points.
On top of that I'll be getting a $25 RZ cerrtificate for making my first purchase on the credit card, meaning I just netted about $35 in bonuses on a $129 purchase.
