While Amazon won't release numbers, an enterprising
commenter on Engadget comes to this conclusion based on
data released by Amazon's e-ink manufacturer.
The Taiwan-based company said its current monthly shipments of 6-inch EDP modules, priced at US$70-80 each, amount to 60,000-80,000 units, with 60% going to Amazon and 40% to Sony.
60% of 60,000 units * 6 months since release =
216,000 units sold.
