Be prepared for sticker shock in your supermarket's dairy section. There is a possible increase of as much as 60 cents a gallon which could push the price of milk close to $5 or $6 a gallon in March.

NBCNews.com reports that the increase is partly the result of smaller herds, feed prices going up, and farmers cutting back on their number of cows. Demand from other countries is also putting pressure on milk prices.

One dairy analyst says after peaking, milk prices should decrease through December.
