Chocolate Milk went up a whopping .50 cents!

What is the deal?! Yogurt already went up .02 cents, and now chocolate milk is up .50! So I didn't buy any the other night. Nestle's chocolate milk was already a deal at our local HEB and was always $2.99, whereas it was usually $3.19 or more at Kroger. But now that it's at $3.49 at the HEB I don't know that we need it anymore. By not buying it I have to send a message to the grocers, or the distributors, or whoever the message needs to be sent to that there is no call for choc. milk to go up by that much, that fast.
