Walmart offers the Board Dudes 18x22" Magnetic Dry Erase Corx Board for $9.48. Opt for in-store pickup to avoid the $5.99 shipping charge. (Amazon offers it for the same price with free shipping for Prime members with a one to two month ship time.) That's the lowest price we could find by $9. It includes mounting hardware and both cork and metal framing for additional note space.
