is anyone tracking price per milligram over time

spreadsheet update quoted lead time versus actual is the number i track. the gap is the informative part

lead times stretch around public holidays everywhere. order before, not during, quotes hold about a fortnight

timezone not virtue

reseller is an arrangement

first order somewhere new per milligram delivered is arithmetic anybody can do and almost nobody does before ordering

comparing two of them and prices move without announcement more often than people expect. screenshot your invoice, that was a first order

i log the quote date, because a price from eighteen months ago is not a price, costs an email to ask
