Link your PayPal account to Samsung Pay and receive a $5 PayPal Credit. (In the Samsung Pay app, scroll down to "Promotions" to find this offer; link is for reference only.) It's a fairly easy way to acquire some free money, which you can spend at retail stores that accept Samsung Pay. The PayPal credit will be added to your account within 24 hours; you'll have 14 days to spend it once you link accounts.
