This avex PDF states the real sales of A BEST 2 by March 2007 (the sales that avex/ayu got money on)
A BEST 2 -WHITE- + DVD - 600,000
A BEST 2 -WHITE CD only - 310,000
A BEST 2 -BLACK- + DVD - 600,000
A BEST 2 -BLACK- CD only - 320,000
1,800,0000 in total.
They state that it brought more value than other regular products. XD
AND they say that even with the really high price, the contents are really appealing so it brought up good sales with even such a price!
In other words the projects' sales were really good and the most money inserting albums this year of an avex artist I suppose.
Even with kumi and the avex's boy bands around, ayu is still avex's secret weapon XD
