Well you can get them for free from the haters and the bigots out there - you just have to catch them because those silly folks are currently only delivering these milkshakes via air drop lolz.
All you have to do is not be a hater or a bigot or a racist like they are. Then they'll call you one, hate you, and deliver your free beverage.
Yum yumz!
You can haz #cheezburgerz! π
