Walmart offers this Mechanical Personal Bathroom Scale in White, model no. BR2016WH, for $3.16. (Black is available for about a buck more.) Opt for in-store pickup to dodge the $4.97 shipping fee. That's a buck under our mention from three weeks ago and the lowest price we've seen for any mechanical bathroom scale. (It's also $6 below the best deal we could find for a similar scale elsewhere.) It features a PVC foot mat and 300-lb. weight capacity.
