Some notes:

1) Ignore the left list, that was for the previous tree. For this week, Anbu would cost on average 5.3k (including the 1k value of weekly free draws).
2) Coin chance of 0.5 for level 7 was for previous tree as well since it used to drop a 10 coin option (though that shouldnt impact 99.99% of users here :P)
3) The "total cost" of the Nov 9 items are based on a player starting fresh from a tree. Obviously if you're getting like Kisame + Anbu it isnt a straight summation of both "Total Cost" items.
4) This is an approximation only based on the average odds of coin drops assuming non weighting of options, and your luck for the day.
