As Quincy said, you have to share your Walmart.com login with your family member(s). You'll also be trusting your family to not nose through your purchase history as they look up their own, and you'll be trusting them to use their payment card instead of yours. If you trust your family enough to do this, simply go to Addresses and add their name/physical address, then tell your family member to add their payment card in the Wallet. Be aware that anyone who uses your Walmart+ will be asked if your associate discount should be applied as they begin checkout. Improper use of your associate discount can result in termination, so be sure your family member(s) understand whether they qualify to use your discount as they shop on your Walmart+ account.

Just got an email yesterday thanking me for signing up for Walmart+. Like you, I never did. When I called my bank, they told me it was definitely fraudulent because they'd gotten quite a few calls about the same thing from others already, and they could see that whoever put the charge through had to try it 3 times before it went through (declined twice). When I called Walmart about it, they put me through to their "fraud department," and what was the first thing they tried to do? Entice me to keep the plus membership by extending it for an additional 6 months. Sure sounds like they are pulling a Wells Fargo stunt! Let's sign people up without their consent, but let's not get caught like Wells Fargo! More on reddit.com
