It cost $2 for one.
The milk chocolate and marshmallow are already pre-melted in an pretty uniform fashion before you order them. From what I saw from the stack they display, the chocolate and marshmallow ratio and distribution is more or less even.
To heat them up, they offer to warm the s'more by the oven. Mine could have used a little more time by the fire as it was just lukewarm.
Both the chocolate and the marshmallow are just melted through (due to the pre-cooking) so you get a wonderful sweet and chocolate gooey-ness.
Overall, Blaze Pizza's S'more Pie was excellent and as good a rendition as I've seen. While you can easily make something similar at home, the price isn't too bad and they're very well made.
