Walmart is clearancing some kids electric ride on vehicles. The pricing seems to vary across zipcodes. I picked up the John Deere Gator a few days ago at my local store (Kitsap County, WA) and the kids love it. I would not say it is worth the original $400 MSRP, but at $150 it was a sweet deal.
The pricing on the site is listed as the "online pickup discount", but my store had the clearance pricing posted on the box.
Some items I found:
Peg Perego John Deere Gator XUV 12-volt Battery-Powered Ride-On: $150
24V Disney Princess Carriage Ride-On: $198
Disney Frozen 12-Volt Ride-On Sleigh: $99
