<prompt> Human: I got notified by Mint that 3 of my credit cards raised their interest at the same time. They did this because the Prime rate was adjusted this week. I was able to negotiate lower interest by asking politely, you might be too! Also, if you dont know, its good practice to call your credit cards every 6 months and inquire about interest rate reductions for your accounts.  <response>: Why do you care what the interest rate is on your credit cards? Are you carrying a balance?
