So you’re extrapolating an answer based on just two days of sales for a store that has just under 6000 items for sale?
No, based on the bricklink order number (ex. Order #4629686) assigned to orders PLACED on consecutive days. One day I placed an order that was assigned number x and the next day I placed and order that was assigned the number x + y. I am looking for y.
But since y’all would rather debate the question than venture to provide an answer, Brave Sir Tim not withstanding, I will give you my estimate based on a single data point: its on the order of magnitude of 10,000 orders placed per day.
