Encountering "Unfortunately, the voucher may not be redeemed one more time"?

This error occurs when Netcup locks a coupon code inside your active browser session cookies after an interrupted or canceled checkout attempt. You do not need to contact support to fix this:

  1. Open https://www.netcup.com/en/checkout/cart and click the red trash icon to empty your cart completely.
  2. Clear browser cookies for netcup.com (or open a new Incognito / Private browsing window).
  3. Return to netcup.vip and copy a fresh coupon code to complete checkout.
