Walmart offers the Weight Gurus Smartphone-Connected Digital Bathroom Scale in Black, Chevron, or White, model no. 0364, for $28.88. Choose Site-to-Store pickup to avoid the $4.97 shipping charge. (Become Gurus via Amazon charges around $1 more for Prime members.) That's the lowest total price we could find by $19, although we saw it for $9 less a month ago. It features an LCD screen, iPhone or Android app, auto user detect for up to eight users, four sensors, and 400-lb. capacity.
