Is Shein Coupon Finder safe?

Medium risk

This extension tests available Shein discount codes at checkout and applies the best one to your cart.

When you shop on Shein, it lets you click “Check them all” on the checkout page to try promotional codes and apply one automatically. The description says it may use affiliate links and collect cashback on purchases where the user has not claimed it.

Shared hosts - 1 hostname

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.

  • Tab visibility
