This looks like a great deal. Will definitely be hitting it for 4Q tax estimates.
I also just confirmed the following via chat: The referred friend does not need to apply for the same card you referred from to get the 3 MR bonus. So if you refer from Every Day Preferred but the friend applies for regular Every Day card you are still eligible for the 3 extra MRs. The 3 month clock for bonus MRs starts the day the referred friend is approved.
