Local Stores Milking You for Milk?

If you go for organic milk, you may want to check out this Brokelyn rundown on prices at area markets by neighbor Faye Penn. She found the prices vary by almost $2 for the same product, and that the C-Town on East 16th is the priciest, where a half gallon of Stonyfield will run you $6.29! She found the cheapest prices at the Key Food on Foster and the Met on Cortelyou.

Is there anything else you see that kind of price disparity on? And do you tend to shop for particular items at different stores because of it?
