My primary card is the AMEX Platinum. I put probably 95% of my purchases on that card. I wanted a Visa that would offer us something unique, and since we enjoy Starbucks it will be nice to get some free drinks and other benefits. It is both a Visa and Starbucks card, so what you earn on the Visa side automatically gets converted to Starbucks "money".
$25 in Starbucks rewards after first purchase. Ability to earn up to 3% with "Automatic reloads", which I am a bit unclear about at this point.
