You can figure sales out from the financial filings. Open the quarter reports for Q1 Q2 and Q3 of 2017 and around page 14 and 15 you see the quarter results and the cumulation report for the year
Q1 sold $0 Q2 sold $1440 profit $203 Q3 sold $1760 profit $704
They have an inventory of about $30,427 left after Q3. This is how much they paid for that inventory. Just guessing by looking at Q3 they are making about 40 cents profit on the dollar for their product. So they are sitting on 30427 x .40 = $12,170.80 profit at the moment.
