Walmart offers the Ozark Trail Eagle 40-Liter Hiking Backpack in Blue for $29.95. Opt for in-store pickup to dodge the $5.99 shipping fee. (Alternatively, you can pad your order over $35 to bag free shipping.) That's the lowest price we could find by $17, although we saw it for $4 less last July. It features a waist belt with zippered pockets, air-mesh shoulder straps, adjustable back panel, and rain cover.
If you work in any of these professions, look out: Your livelihood may be in danger.
