Buy now, pay later online options gaining in popularity

If you can't afford something, should you get it anyway? Online services are making that more and more possible, but it's becoming a concern as bigger industries consider letting you leverage it for bigger purchases. Companies like Afterpay, and Klarna are technically operating outside the legal definition of a loan, so they play by different rules. The health care world is also keeping a close eye on the popularity of these options because they're considering allowing something similar for medical bills.
