<prompt> Human: I was paying my credit card bill online and I found a link on the Bank of America website said I had unredeemed cash rewards, several hundred dollars. I had never noticed this before. It gave me a few options for how to redeem it, it said they could send me a personal check in the mail or I could deposit this money directly into my savings account with the bank. It says I get 1 cash back for every purchase I make, and 2-3 for certain purchases.Is this really how it works? I get paid a small bonus every time I spend money using my credit card? And its just free money no strings attached? I was always taught if it sounds too good to be true, it is too good to be true. I suppose its not that much money, because I think these hundreds of dollars were earned over like five years since I first got this credit card. Still, whats the angle here?EDIT: Disclaimer. This is not native advertising. Bank of America is a racist redlining predatory-lending family-evicting pack of jackals. This was a genuine question I asked in good faith and did not expect to get huge like this. Assistant: Many good credit cards have rewards of various kinds. There are several cash back cards and it seems you have one of them.The angle is that it is the credit card issuers way of enticing you to use their card, as opposed to a different card that you could get different rewards on.Human: And theres really no strings attached? By accepting this money I havent agreed to anything weird? I probably sound paranoid but I just wanna know for sure.  <response>: Nothing weird and no strings!If you want to see the wild world of credit card rewards in all of its magnificent glory, head over to rchurning to see what types of rewards they get! It will probably help to reassure you that such a card is normal and ordinary.
