You can’t go wrong with gift cards. They’re versatile and they’re well appreciated. When you can’t figure out what to get the millennial that has everything, you can purchase them a refillable gift card that can be used anywhere their heart desires. When you know your millennial’s favorite place to shop, get them a gift card for their favorite store and let them run wild. They’ll appreciate it and it’s a lot more reliable than buying a gift they’ll just return anyway.
