Here's a new idea for a holiday stocking stuffer: a gift voucher for stock.

Stockpile.com is now selling a physical gift card for shares of stock. Not unlike iTunes and retail stores, Stockpile gift cards come in denominations ranging from $25 to $100, and can be purchased on the checkout line of retailers like Kmart and Toys 'R Us.

Once purchased, the receiver then logs online, signs up for a Stockpile Investments brokerage account and redeems the purchased amount for a fraction of the stock. Stockpile co-founder and CEO Avi Lele sees the site as a way to help democratize investing for retail buyers.

"We're seeing young people coming in getting gift cards, or coming in on their own, and buying $25, $50, $200 worth of their favorite stocks to start investing early," Lele told CNBC's "Closing Bell" in an interview last week. "It's much better to start [investing] in your 20s than in your 30s or 40s," Lele said.

Lele said people over 30 are buying the gift cards for people under the age of 30. Shares of Apple, Facebook and Google, which now trades under Alphabet, are the most popular with Stockpile card recipients.
