我没在亚马逊开店,但是从你提供的英文文字来看,标准运费是4.83美元,如果你成交了,退还运费4.49美元(所以上面写的是Credit). 也就是物品成交后,你售价30美元的东西,卖家拿到的是$30-亚马逊收取的佣金(不同产品收取不同佣金比例)-0.34的运费费用
I don't have a store on Amazon, but from the English text you provided, the standard shipping fee is $4.83. If you make a deal, $4.49 will be refunded (so it says Credit). That is, after the item is sold, if you sell it for $30, the seller gets $30 - Amazon's commission (different products have different commission rates) - 0.34 shipping fee
