Walmart offers the Summer Infant Lil' Loo Potty in Teal/White, model no. 19140, for $6.78. Opt for in-store pickup to dodge the $4.97 shipping charge. (Amazon offers the same with free shipping for Prime members only, and with a 1-3 month shipping delay.) That's the lowest total price we could find by $10. This unisex training chair features a removable pot, high back, and splash guard.
