Fun report: I tried to buy something off Newegg with BitPay again today. Selected Nunchuk wallet, gave me an error, then flipped out and wanted me to create a BitPay account. I cancelled the tx and just used a credit card 🤦‍♂️. I left feedback on Newegg's site to use Opennode or BTCPayServer, because I've not once had success using BitPay on their site.
