OXA Home via Amazon offers the OXA Ultralight 30-Liter Foldable Daypack in several colors (Black pictured) for $19.99. Coupon code "ZW9QKAFH" cuts it to $13.99. With free shipping for Prime members, that's the lowest price we could find by $7, although we saw it for a buck less in September. It features eight pockets and adjustable padded shoulder straps. Deal ends December 31.

Update: The coupon has expired; however, the price has since dropped to $13.99.
