Free scoop of ice cream at Ben and Jerry's wyb $10 in gift cards

Ben & Jerry's ice cream shops are offering a free scoop of ice cream when you spend $10 or more on gift cards.  That sounds like a sweet treat for purchasing gift cards:) The website didn't list how long this offer lasted.  I would assume through the holiday's or the first of the year. There is a great from "cow to cone" video on the website that is about 10 -15 minutes long that would be wonderful for young children or those homeschooling to watch.
