I believe the console is $250.00, the Wii Fit anywhere from $80-$130. The games are $40-$60 each. Our console was a Christmas present from my MIL to my son so some of the numbers are a google guess
We bought the Wii Fit from Sam's for $120.00, it included a game we didn't want - so my unscrupulous husband returned it to Walmart for $60.00, costing us $60.00 in the end.
I wouldn't have bought it on my own - spendier than a year's membership at the gym! My MIL spares no expense on my son though - so we lucked out.
