This is the one time of the year you can purchase poster board at a discounted rate.
Rarely if ever do stores discount poster board.
While not much, any discount is good, right?
Poster board is tax exempt during the Sales Tax Holiday.
Also if you're a book lover -- books with an ISBN and under $30 are tax exempt too.

(Don't forget Jefferson County is not participating. You'll still pay a 2 percent sales tax on tax exempt purchases made in the county. Go here to see the list of cities and counties not participating in the holiday.)
