For the email, you can use an email alias service like Addy or SimpleLogin. They're both open-source and offer free tiers. I never give out my real email to anyone now except actual contacts.
After that, I think a VPN would probably still work to disguise what you're doing from Walmart, but I'm not a 100% certain on that so I won't link any.
But yeah, definitely use email alias wherever you can.
