Amazon offers its Amazon Prime members Active Life: Extreme Challenge Bundle with Mat for Nintendo Wii, model no. 80015, for $11.48 with free shipping. (Non-members can spend $25 or more to qualify for free shipping; otherwise, shipping costs $4.98.) That's $1 under our December mention and the lowest total price we've seen. (It's also a current price low by $23.) In-game activities include street luge/in-line skating, kite surfing, base jumping, acrobatic double dutch, and more.

Amazon Prime membership is $79 per year; however, Prime is free for college students for six months, and free for parents and caregivers for three months. (Note that currently there's a waitlist for Amazon Mom.)
