<prompt> Human: I currently have capital one platinum with 1.5 cash back on every purchase, and im looking for a bit more. I spend about 1200 a month and pay it off. I spent about 17000 in 2017 and paid 0 in interest, so I have a pretty good handle on my spending. Im just trying to make the best out of my spending, especially since in November and December Ill be making a couple big purchases, somewhere to the tune of 4-5000, so Id be able to make the best out of any type of rewards with a minimum. Im just having trouble sorting through the different offers. Any advice??  <response>: I go for simplicity. Amazon store card saves me 5 on all Amazon purchases. I use Citi Double Cash 2 for everything else.
