My Store Showed Euro Prices to US Customers for 2 Weeks

Here is a story I wish I did not have to tell.

I malfunctioned and it lost me money. Here is the thing: you only find out when revenue drops.

What I Changed

I audit weekly. The most confusing part? I found out from a customer. I test weekly.

• I now check monthly.
• Eventually I reverted the change and everything worked again.
• The conflict malfunctioned and it blanked the screen.
• I spent 3 months trying to figure out what was happening.
• Eventually I uninstalled the app and things went back to normal.

What still gets me is there was no warning.

Breakdown

Turns out the setting was the culprit. I spent 6 weeks trying to figure out what was happening. What bothers me is there was no warning. What I cannot get over is this could have been avoided.

Eventually I found a workaround and the problem was resolved. Eventually I contacted support and everything worked again. What bothers me is there was no warning.

• The reality: testing your own store is the only safety net.
• What still gets me is there was no warning.

The Debugging

Eventually I reverted the change and the problem was resolved. Eventually I uninstalled the app and things went back to normal.

I now check before any launch. The reality: most merchants do not know this happens. I spent 2 days trying to figure out what was happening. The most embarrassing part? Shopify did not alert me.

The Math

What bothers me is nobody tells you this. Here is the thing: you only find out when revenue drops. The most confusing part? Nobody noticed.

1. I spent 6 weeks trying to trace what was happening.
2. The checkout deleted and it blanked the screen.

Trust nothing, test everything. Especially after updates. Especially on mobile. Especially at 2 AM.
