Actually, some barcodes do contain the price. EAN has several ranges allocated for this purpose to be used where the the price can vary by item, for example whole chicken. At least one large retailer I know of uses their own barcode system that contains the price, when they want to change the price, they put a new barcode sticker over the old, this works well for them because their business model is slightly off the norm. So whilst in the general case the barcode should not contain the price, under some circumstances it is perfectly reasonable for a retailer to have the price in the barcode.

Does that include CDs?:)
Now just imagine if the RFID tag were also used as part of an RIAA mandated antipiracy machanism, on second thoughts, maybe I don't want to go there or maybe I should have patented it.
It is called EPC and is being worked on by these guys. Though I doubt it is quite as fancy as XML with the limited memory capacity on most of the cheap transponders.

That is amazing, it is almost indistinguishable from the original!
Maybe I'm gettin' old.
