Walmart offers the BabyBjörn Potty Chair in White for $17.50. To cut the price to $13.33, opt for in-store pickup. That's at least $4 less than you'd pay at another local retail store, although in September we saw it for pennies less. It features a built-in splash guard.

Update: Amazon offers it for $13.60 the same price with free shipping for Prime members.
