Amazon Best Seller Drainspotting now at no 4

So it seems to go up and down quite a bit, but Drainspotting is still sitting in the top 10 of the Amazon Best Sellers List for the last Month or so, under Asian Photography. It is also floating around the 40 - 50 mark for categories Architecture and photojournalism and has been doing this for about a month or two. I have not seen it at no 1 yet, but chances are it has been there, because they update this hourly. I only started checking it recently. If anyone knows if there is a graph of sorts, please let me know.

No 3 on Amazon Best sellers in photography Asia

Last week Drainspotting Hit No 3 as  best seller In the catagory of photography, Asia. It has now dropped to no 12 but as last week was the first time i ever checked the result, i wonder if it was ever no 1. i cant seem to find a best seller graph.


Anyway, no 12 still isnt bad. It stayed up as no 3 for a over a week as far as i know.
If anyone knows how to check the history of best sellers on Amazon, please let us know.
