Yeah what actually happened here? This note isn’t doing anything more than describing bitcoin working normally

Yes, I got four separate emails telling me that I owed somewhere between 1,000 to 1,600 sats because the fiat price of the Bitcoin I paid them must have gone down a little. They're squabbling about an amount of Bitcoin valued in fiat between $0.80 and $1.50... I just paid $26 in shipping. Like wtf...
