11. Scan Your Register Receipt

Submitting receipt photos to apps like Fetch Rewards can earn you free Walmart gift cards. These apps use receipt data to analyze consumer behavior. Fetch Rewards is top-rated, giving you at least 25 points per receipt. Uploading is quick, and you can cash out at 3,000 points for gift cards, magazine subscriptions, charity donations, or sweepstakes entries. This means 120 receipts without bonus points, so expect to earn a few gift cards per year with regular use.
