As much as I checked, costing of T9531-CGA1-D203 (@610B by 5p order) is quite "impossible" price.
Because it has quite same structure with another T9531-CGA1-D205/D206 (@5,610 BY 5p order).
And some items shows too cheap price setting, far from our general pricing level.
(If your strategic costing, OK. But I'm quite blind of information between you and Ms.Phat. Then, need to inquire you back before final confirmation to customer.)
