conversation: User (Windrider904): "Hey guys, I recently got a Amazon Prime Store Card to slowly build up my credit. I'm really only purchasing things I know I can pay back within a few weeks. \n\nI know you have the option for 0% interest for 6 months on $149 or higher payments, but the item I got was only $120. If I can pay it back next week, will I still be charged interest since I couldn't choose an option like the above one ? \n\nI've been hearing sketchy things about this card and hopefully I don't regret it, being a loyal Prime member for years I thought it would be a great idea to get my credit up. Any help would be awesome, thanks guys!"
  Self: "This is what I could find about the interest calcs for the [Store Card](https://www.synchronybankterms.com/gecrbterms/pdf/AmazonCreditCard.pdf), check the PDF for full terms and conditions.\n\n&gt; How We Will Calculate Your Balance: We use a method called “daily balance”.\n\n[...]\n\n&gt; The APR for purchases is the prime rate plus 22.74%. We use a daily rate to calculate the interest on the balance on your account\neach day. The daily rate for purchases is the APR times 1/365. As of January 1, 2017 the daily rate for purchases was .07258%\n(APR 26.49%). Interest will be imposed in amounts or at rates not in excess of those permitted by applicable law.\n\n[...]\n\n&gt; We charge interest on your purchases from the date you make the purchase until you pay the purchase in full. See exceptions below.\n\n&gt; • We will not charge you interest during a billing cycle on any purchases if:\n\n&gt; 1. You had no balance at the start of the billing cycle; OR\n&gt; 2. You had a balance at the start of the billing cycle and you paid that balance in full by the due date in that billing cycle.\n\n[...]\n\n&gt; We charge a minimum of $1.50 of interest in any billing cycle in which you owe interest. This charge is added proportionately to each balance type."
