1 打开京东APP或官网，登录账号；

2 进入“我的服务”-“回收服务”，选择您要回收的商品；

3 进入商品详情页，上传商品照片并确认回收价格；

4 选择收货地址，提交回收订单；

5 京东会尽快安排快递上门取件，送至京东回收中心；

6 经过初步检测后，京东会向您开具发票并支付回收金额；

7 如果发现商品有质量问题，京东会及时将相关检测报告发送至您的手机。

不会。根据查询公开信息显示，淘宝平台上的虚拟物品多数都是数字或者代码，发放后无法收回。如果出现了卖家欺诈行为，如虚假宣传、不提供商品等情况，可以向淘宝客服投诉，协商退款事宜。同时，在购买虚拟商品的时候，建议仔细看清商品描述、评价等信息，避免购买后后悔。
