<prompt> Human: I recently was approved for 1400 on my new Amazon store card. As a full-time student that frequently orders from Amazon, I was planning to use this to help slowly build my credit. When I googled around, I saw a lot of mixed reviews on different ways to build credit - only charge a small of your max, make large purchases, pay it all off immediately, float a small balance... I am not really sure what to believe. So, rpersonalfinance, how can I use this to best work on my credit?  <response>: Right, theres a lot of bullshit and misinformation out there. Only charge a small portion of your limit every month, and only on things you were going to buy with cash anyway. At the end of the month, when you get your statement, pay off the entire balance in full. Do that every month, and dont ever make a late payment, and your credit will be great.
