This Refurbished Sun Joe 16" Cordless 40V Lawn Mower (model ION16LM), which is listed at $299.99, drops from $189.99 to $184.99 at Yugster. Plus it ships for free. New ones go for at least $270 (compare here). This mower includes a rechargeable lithium-ion battery (many refurbished models do not) that allows you to mow up to 40 minutes on a single charge. It has a six-position height adjustment lever and a brushless motor which decreases noise and extends motor life. Better yet, there's no sales tax (except UT).
