Error on purchase via web store

Hello! 

When I attempt to purchase the nightsister LSB on the web store I am greeted with an error splash screen. I've attached screenshots of the console logs and network traffic that occur on click of `Buy Now`

Repro steps:

• Open web store
• Scroll down to Nightsister LSB
• Click Nightsister LSB
•  In the preview modal click `Buy Now`
• Observe "Oops Something went wrong"

Thanks!
