DVD price in Beijing, 9/4/05

I went to CarreFour, a European warehouse shop in Beijing. I found that the DVD price is about 1/8 of that in the States. For example in the picture, Matrix DVD cost about 22 RMB Yuan, divided by 8 Yuan per Dollar exchange rate, each copy is approximately equal to $2.5. same DVD might cost $20. Similar low prices are on Coke, seafood, etc..
