Just saw this at my local store and picked up two as gifts at 30 each. Checked brickseek and it looks like only this Wal-Mart in my area has them on sale at that price. They had two full pallets by the front with a rollback sign.
Looks like other stores and online it's 50 which is still a decent deal if you need a backup or starter set.
