In response to McDonalds getting into the smoothie business, Jamba Juice recently launched a parody campaign advertising cheeseburger smoothies. They will also accept all McDonalds smoothie coupons at locations in Los Angeles, San Diego, San Francisco, Sacramento, New York, Chicago, Denver, and Miami until August 15th. This includes the free smoothie coupons that were in the Sunday newspaper Parade section a few weekends ago. You can find more details at cheeseburgerchill.com.
If you don’t live in one of the participating cities, you can still get a $1 off coupon for any of their 30+ smoothies.
