The highly-recommended BabyBjorn Potty Chair is discounted up to 33% off right now. You can pick up the Green or Blue potty chair for just $18.81. That's 33% off the regular price of $27.95. If you need a different color, Pink, White and Red are all $22.99, which is still 18% off the list price.
My sister told me a few months ago that this is the “best potty chair”! She should know, she's successfully potty trained 4 kids! Shipping is free when you spend $25 or more.
