Based on the photo, my estimated calculation is there are at least 1440 bottles of oil.
My rough guess is that the cost price of each bottle of oil is less than $5 (or even much lesser, maybe only $2)
Hence total cost is estimated around $7,200
Let's say each bottle selling at $20/bottle, this chap is gonna make at least (1440 x $20) - $7,200 = $21,600.
Very good money indeed maybe selling much better than those Thai NMP Oil.
