I've been using the Chase Freedom rewards card most of the time, and the extra 10% + 10 points per purchase adds up for me. From the latest month of purchases:
Points earned on purchases 898
10% Bonus Points per $1 You Spend 90
Bonus 10 Points on Every Purchase 470
Bonus from 5% categories: Jan - Mar 377
So I received just over 2% back. Not bad. 30% of my total points were generated via the 10% + 10 point per purchase bonuses for being a Chase checking customer. This is a great small purchase card. For example, a small $10 purchase will net you 2.1% back, and a $5 purchase will get you 3.1% back, and a $1 purchase gets you any amazing 11.1% back!
This card (with the checking customer bonuses) combined with the AMEX Blue Cash Everyday make a great combo.
