Walmart offers the Step2 Up & Down Roller Coaster for $96.99 with free shipping. (Amazon charges the same.) That's the lowest total price we could find by $9, although we saw it for $29 less for Sam's Club members during Black Friday week. It features non-slip steps, 3-piece 10-foot track, recessed retainer wells, and car with handrail and foot rests.
Amazon offers Prime members the Step2 Play Up Teeter Totter for $33.99 with free shipping. (Non-members can qualify for free shipping with orders of $35 or more; otherwise, shipping adds $11.24.) That's the lowest total price we could find by $10. It features two contoured seats with handle bars and a weight capacity of 162 lbs.
