<prompt> Human: This may not work, and I hope someone can explain to me why it wouldnt but hear me out. Last week I sent my sister 300 with my credit card through paypal and she picked it up no problem.What if I took out a credit card, sent the maximum amount possible to My wifesistersomeone I trust, and have them send it right back to me at the end of the month, possibly using their own credit card. I would pay my bill with the money she sent me and in a few days, start the process all over again. We would both be building credit without any actual risk.  <response>: Paypal transfer fees make this a horrible idea, even if it would work. A better option would be to simply pay for all of your expenses throughout the month and pay off the card when the bill is due.
