亿恩小编接到卖家爆料，自己参加亚马逊促销活动，活动结束后下载订单仔细查看的时候发现：自己设置的折扣是10%，但3000+usd的FBA订单下载下来金额是0，还亏了AM FEE……

圣诞节要到了，亚马逊邀请卖家做慈善回馈当地消费者的吗。什么情况？发生了什么？亚马逊promotion系统bug？

这个卖家赶紧去后台查看订单，发现客人买了多少钱promotion就返点了多少，这个产品是有参加promotion活动的，满25usd 10%off。

查看了其他客人订单，满25usd的都正常10%off：

唯独下面这张订单全返，而且很奇怪，其他订单只会出现一项promo rebates

唯独这张订单对应了两项promo rebates，两项相加刚好等于产品的金额。

这位卖家说：我们不确定是不是亚马逊promotion出现漏洞，问了亚马逊客服，客服了解情况后说转到内部调查了，现在我们也只能等亚马逊调查结果了。

该卖家确认自己的设置没有问题，之前参加的促销都是正常的：

用了劵码之后的订单是这样的：

Claim Codes and Combinability

Claim codes are keys that allow a discount to be applied to an order. The buyer must enter the code at checkout to benefit from the promotion.

You specify whether or not to require a claim code when you create your promotion. If you require that a buyer enters a claim code, you can limit the promotion to one redemption per buyer. You also can allow customers to enter multiple claim codes for increased savings.

As a general rule:

· If a promotion does not require a claim code, it will combine with all of your promotions that do not require claim codes.

· If your promotion does require a claim code, it will combine with all of your promotions that do not require claim codes and with some or all of your promotions that do require claim codes.

Combining Claim Codes

Depending on how you create your claim code rules, buyers can combine your available claim codes to receive higher discounts. When allowing multiple claim codes on the same items, be careful because unintended deductions can occur.

Preferential

· Combines with all Unrestricted claim codes.

· Combines with all promotions without claim codes.

· If there are multiple Preferential claim codes, the most beneficial promotion is applied.

Unrestricted

· Combines with all Unrestricted claim codes.

· Combines with one Preferential claim code.

· Combines with all promotions without claim codes.
