请问用过带costco会员的americanexpress的朋友，这里有一个关于该卡本身的cash rebate的问题。去年我得到了basic rebate, 但bonus rebate却没有得到。以下是摘录的rebate计算的内容，是否我只要每月付帐单时，就pay一部分，留下一点balance到下个月，哪怕只有$1.00，我就可以从新的消费中得到0。5％的bonus rebate?留balance会不会对credit record有影响？
谢谢了！
Here's how your rebate works:
Basic Rebate: Annual Net Eligible Purchases % Cash Rebate
On the first $2,000 0.25%
On the next $3,000 0.50%
On any amount over $5,000 1.50%
The annual maximum Basic Rebate amount is $500.
Bonus Rebate:
0.5% on all net eligible new purchases when you carry a balance. The annual maximum Bonus Rebate amount is $125.
