真正的永动机 4%+ return

     
    topcashback给giftcard 1.5% cashback.自己先注册这个。
     
    先用FIA 在 amex买amex giftcard, 2.4% fia cashback +1.5% topcashback
    等收到卡之后，用amex giftcard 买 visa giftcard，1.5% topcashback
    拿到visa gift card之后去walmart或者其他地方买money orders,然后直接存银行。
    总共是5.4% cashback.减去fee,shipping.
    最后算下来 4%的return还是有的。
    举例：
    买3000x2 amex gift card,fee 7.9, shipping 8.95
    收到卡后，分两次买visa giftcard
    每次$2981，fee 11.85,shipping 6.72
    最后去walmart 买money order，费用可以或略
    fia cashback = (6000+7.9+8.95)*2.4% = 144.4
    topcashback = 90x2 = 180
    总花费6016.85+money order fee
    Money order $2981x2
    总共cost大概$60.
    净收入$265.大概4.4%
    每个月搞两次。$500块。唯一需要出门的就是去买money order
