California plastic/glass & Alum prices

I wonder how some (new) yards here in Tucson can pay so much for certain items. I thought maybe they were shipping the items to California illeagly. But not sure now that I have seen the prices...
Statewide Average Monthly Scrap Value Notice

Some odd prices by me but I will take it when I can get it are...
#1 plastic bottles .30 lb (Calif average is .25 lb)
#2 plastic milk/water .08 lb (Calif average is .187 lb)
#2 plastic color .02-.05 lb (Calif average is .187 lb)
Glass bottles/jars .06 lb (Calif average is .0015)
aluminum cans .80 - .90 lb! (Calif average is .80 lb)

Unless they are taking them for the deposit value but some items have no CA redemption value

no minimus on plastic. Some guys are doing well with glass they pick up from bars and restaurants on a weekly basis
