Hi Harumio here,
We saw some traffic to our site coming from here, so we registered an account to engage directly and get some feedback and suggestions.
To answer a few questions,
1. Our pricing might differ from Google exchange rate because Google uses mid-market rate, which is significantly "cheaper" than what PayPal / Credit card companies actually charge us. We could offer a US bank wire transfer option but that's usually reserved for bulk orders of 10 adapters and above.
2. Based on our past experience, there shouldn't be any tax/duties for USA customers but Canada would probably have taxes/duties.
3. If there's demand for it, we can organize a group buy but a member of the community would need to offer their Tesla account in order for us to purchase the adapters.
If there's any questions, please feel free to ask.
Thank you!
