For those requesting tickets from Populuxe:
If you're outside the US, you need a VPN to upload the image of your purchase receipt. Without a VPN, you won't see anything on the Trolli Xbox website.
It will ask you to upload the image of the receipt and enter the address where you live.
I entered a different street address than the one on the receipt, but within the same ZIP code.
You will receive an email that says that your submission was received and they're supposed to send the code to the email address you used to register within 7-10 days.
But in my case, those days have passed and I haven't received anything.
Even so, thanks
