<prompt> Human: Hello can someone help me I have a question I have a few credit card with credit available on them to use and I am going to use them to buy groceries what am I best doing please paying for the transaction with my credit card or withdrawing the cash from a cash machine and paying cash which is the best way with lower interest  <response>: Please read the second link in the auto-moderator response.This question shows you dont really understand how credit cards work. Nothing bad against you, you just dont have the information you need. Learn what you need to from that excellent link and act accordingly.If you mis-use credit cards because you dont understand them properly, they will destroy your financial life. If you use them well, they are a really good tool.The short answer to your question is to never, ever use credit cards for a cash advance. There is an immediate fee for cash advances, and you start paying really high interest right away. Buy your groceries by paying with the card at the store. There is no fee and if you pay the full bill payment not the minimum payment on time there will be no interest at all.
