Last Dominos shake deal expired.
Saw them making one of these at my local dominos and was quite intrigued, couldn't cough up the $6 needed normally but for $3 I'll have a try.
This is for the standard Classic Choc Malt or Traditional Malted Vanilla. $1 extra for a sauce swirl and whipped cream.
Can confirm, for $3 it's a really good chocolate shake!
