Walmart offers the BDK Venice Series Car Seat Covers in several colors (Red pictured) for $19.99. Opt for in-store pickup to dodge the $5.99 shipping fee. That's tied with our mention from a month ago and the lowest price we could find by $7. They feature double-stitched seams and a split rear bench.
These freebies are available to anyone with an internet connection — including those without an Amazon Prime membership.
