Google Wallet is trying a new method to spur adoption: giving out free money.

Google Wallet recently started a campaign to give out $5 to consumers who buy gift cards from the following retailers via Google Wallet:

• Regal Cinemas
• Sephora
• Staples
• Toys “R” Us on Gyft.com
• Whole Foods Market

Google Wallet users need to just click the Save to Google button in its app and save an online gift card for the retailers listed above to get the free $5. Redemption must be done within a brick-and-mortar store  of one of the five retailers before the end of January 2015.

The promotion is designed to promote Google Wallet as an app to store gift cards. It is holiday season, after all.
