Where can you find a virtual game for free

For the Wii, there is a price on every Virtual Console Game.

A place that would offer money specifically so you can obtain a Virtual Console Game for free would be rare, knowing that Wii Points (which are used to buy Virtual Console Games are bought with a credit card, if not bought differently at a retailer).

Wii Points can be purchased via the Wii Shop Channel with a credit card (Visa or Mastercard) or at retail with an MSRP of $20 for 2,000 points.
100 Wii Points = $1.00
