<prompt> Human: So Ive recently paid off the majority of my student loans which has freed up 1,000mo. In the interest of keeping my credit score high currently in the 700s I am considering applying for ONE credit card to use for small purchases like gas and food to accumulate reward points. I wouldnt be putting more than 300 on the card each month, gas is 100month and food, right now, is the same.Are there any cards or companies that people recommend? I do not currently have any other credit cards, but I do occasionally use PayPal credit on 12 month payment terms.  <response>: Citi double cash card. 2 cash back on everything. Best all around card, but requires good credit. Capital one quicksilver gives 1.5 with free credit monitoring
