pieces of foam... assorted shapes sizes and prices

back to the boogie board question...

just as lemonade is a riddle to me
bicycles are a riddle to others

here I am stuck on another riddle...
how much or how little can someone spend on a Boogie Board?

I just upgraded my kids from a 10 dollar piece of foam to a 25 dollar piece of foam
NO WAY I AM BUYING THEM A TWO HUNDRED AND TEN DOLLAR PIECE OF FOAM!
