The costs for the bords at various stores are as follows:
Michael's: $4.99
Office Depot: $7.99
Office Max: $8.49
Baker's: I don't remember
All the boards are the same brand: Elmer's
Hope this helps others who are looking for the tri-fold display board!
I'll check on the price and size that we have at the school store.
Thanks for the information,
Cathy
