<prompt> Human: Ive been laying it off monthly and my score is way better. They are offering a credit line increase from 400 - 600 for 19.99. Is this normal? Should I take it?Thanks.  <response>: No way. With any reputable credit card provider you would never have to pay for a credit increase if you qualified for one. Keep using this card, paying it off in full, and get a differentbetter card as your credit history grows.
