Walmart offers the Sterilite 18-Gallon Storage Box 8-Pack in Navy, model no. 17317L08, for $32.94. Choose in-store pickup to avoid the $5.97 shipping fee. That's $6 under last month's mention and the lowest price we could find for an 8-pack now by $19. Each box measures 24" x 18" x 16" and features a snap-on lid.
