I got this e-mail today:
Thank you for taking the time to contact McDonald's. We appreciate your interest in our Shamrock Shake.The Shamrock Shake is a "promotional" product offered for a limited time only. Since the decision to offer promotional products is made on a region by region basis, I have forwarded your comments to the McDonald's regional office in your area for their consideration in deciding if they will offer the Shamrock Shakes to their customers next year.Once again, thank you for taking the time to contact McDonald's and sharing your comments with us. Hopefully, the Shamrock Shake will be offered at your local McDonald's next year.
