大家最近GNC能顺利下单吗？为什么一直有错误提示。。。

用的是快报折扣码DMFEBSALE和VISA2018，但是每次下单都错误提示：We're sorry that your order could not be placed. This probably happened due to a high order volume or temporary connection errors. Please wait a few minutes and resubmit your order. We won't process your payment until you successfully place your order. If you have further questions, please contact us.


美卡，地址尝试过国内，转运和美私，换过帐号，IP和浏览器，都是同样错误提示，为什么我下不了单啊？
大家有同样问题的吗？
