+ 2-packs of chocolate covered graham cookies (I get the great value brand from Wal-mart)
= a snack for about 24 people for less than $10
Of course, you will probably want to provide bowls and spoons. The ice cream should be around five bucks and the chocolate graham cookies are $1.50 per pack.
I like to advertise this in advance, because the name and actual snack will draw people in. Nobody is every disappointed even though it is really simple!
