value

値段(ねだん)	Price of one item. (usually used about a big thing – house, car – moreso than a gumball or a Pocky. In those cases, you’d just say, ‘いくらっすか?’) $$$TTT

価値(かち)	Value in general. Can be used about money (a valuable necklace.) but unlike 価, 価値 has a more broad, non-money feeling to it:this painting has artistic value, she values honesty highly, I made a value judgment, the value of learning has no price-tag. PPP TTT

価(あたい)	Value – but not an actual dollar amount (that’d be 値段(ねだん)), 価 is value as in "The value of the antique goes up with time’ or ‘I’ll estimate the value, using my jeweler’s loupe and tweezers."

値(ね)	Value in a math or science sense! A numerical value. One unit – an angstrom or a light-year.

物価(ぶっか)	Price of a commodity as a whole (Gas prices are up! Tokyo prices are higher than in the countryside!) If you want to talk about the price of one item specifically, you’d use 値段（ねだん）.

価格(かかく)	A very narrow meaning:unit price. Used when talking about business or market conditions. Or if you are a factory manager who is haggling for 10,000 diodes, wholesale. You wouldn’t say to the kid behind the counter at 7-11, ‘What’s the 価格 of this bag of chips, dude?’

小売価格(こうりかかく)	Retail unit price.

卸価格(おろしかかく)	Wholesale price.

値段(ねだん)	PRICE - Use this in stores.
