I'm in SoCal - Riverside/San Diego county areas. The 2,400 tag was seen in Menifee where it is the ONLY bird store for ~50 miles...
More reasonable prices are seen in San Diego county where there are about 6 bird stores all relatively nearby.... Here the prices are ~ 1,800 or so.
I think the boy was being sold for 1,200 due to the fact he is 10 yrs old, and probably set in any bad habits he may already have. The Baby Vos Girl was set at 1,800, and the SI Girl that is still not ready to go home would be 1,600. The lady said if I really liked the Vos instead she'd let her go for 1,700... but I hear they tend to be a little less stable than the SI.
