[Chase Fleming]

Did the storage path change? I made a new blocto account and it worked.

[Mackenzie]

@chasefleming Yes, this could be the issue.

[Hannah]

Yep, it did change: e2a5c91

I've confirmed that we are able to purchase an item without running into this specific error with a new blocto account! I will be closing this issue, and update the README to include this as a warning
