Call your credit card company once a year and tell them you lost the card. You get a new number. That doesn't make it impossible to track or trace your buying habits. But it does make it harder. If they are querying your individual sales records (which they are not unless you are a suspect of a crime) they start with gun related sales, sorted by number. They don't go by name because a lot of people have the same name.
Bear in mind that banks who issue credit cards do not commingle or conjoin their databases in any way. Credit reporting agencies summarize transactions from those databases. They are about tracking your spending and payment habits, not anything at the sales transaction level.
For those who lie awake at night worrying about who gives a shit what they (specifically) are buying, then I suggest legally changing your surname to one of the most common name in the USA: Smith, Johnson, Jones, Brown, Williams. First name? James or Mary is at the top. Move and get a change of address every three years and change your mobile number every two.
The funny thing is I have done nearly all of that but not on purpose. Except change my name. I moved 19 times in 25 years. My grocery store thinks my name is Mr. Potatohead. I never use my real birthday for anything if asked. And I frequently use Visa gift cards to buy ammo and occasionally a firearm.
I use VPN and a dedicated firewall. When I am not using my computer a bot of sorts randomly points my browser to thousands of web sites a day that I have no interest in. Anybody who succeeds in my efforts to foil their tracking will have one Hell of a time figuring out what my genuine interests are.
My second book, following the popular
Why You Can't Get Laid: A Guide for Gen Y Men will be
The Everyday Guide to Avoid the People You Imagine Are Watching You. There's money in paranoia.
