上次写了篇文章[aws入坑](https://www.yuanchengzhushou.cn/article/7968.html)
看到`aws`12个月免费的广告打的火热，于是壮起胆子注册，绑定了信用卡，开始使用
因为只有`15G`的免费流量，所以不敢放手使用。
平时也没有看账单，这两天因为月初，开始留意账单的事情
于是访问`https://console.aws.amazon.com/billing/home#`
发现已经产生了额外的费用$19.5，这足可以购买一年的vps
于是百度，发现很多网友碰到这类问题，想想能不能申请退款之类的。
终于发现是什么原因导致产生了额外的费用
在创建虚拟机时，首先要选择`ami`，一定要仔细认真，就算标了免费，也要认真再三，看看ec2是否收费
由于自己不小心，用了对于`ec2`不免费的`ami`产生了费用，最终选择了`amazon`自己的`ami`
尝试着申请`aws support`，回复速度还是很给力的，对于产生了额外费用的网友，可以试试看，也可能会退款哦
>this is my first time to use aws,
after using it,i find the bill is amazing.
i find that the bill includes aws marketplace fee and aws service fee,
as you know the aws service fee is free,but how about the marketplace fee,
i don't know this service is not free, can you free it ,i think this is a mistake.
or tell we how can i use the aws totally free?
as you know i use the free aws service
why the marketplace service is not free,i feel i am cheated,as it just like a trap
you say free,but it doesn't
i want to pay almost ￥140
or the fee is not correct calculated
you can just fix it
because it makes me worried
i don't want to pay,free it or i don't use aws any more!
很快就有回应，让我给marketplace发邮件，看看他们是否同意退款，收到邮件，目测退款可能性比较大
>Hello,
I'm sorry for any concern caused by the charges related to your CentOS 7 Latest Minimal AMI Marketplace subscription, and I’m happy to help you request a refund.
Software charges for AWS Marketplace subscriptions are paid to the seller of the product, and refunds must be sought from the seller directly. Each Marketplace seller is required to include a refund policy on their Marketplace page:
`https://aws.amazon.com/marketplace/pp/B08JQ86PVQ `
If ProComputers.com approves your refund request, they will submit a form to AWS. Once we receive the form with ProComputers.com's approval to do so, we will process the refund.
