#92Well, as long as people realize their data is sold by food markets, I am personally OK with it. That said, to not get the discounts (thus not sharing your information) is leaving money on the table. Also, if you are not part of a loyalty program, and you use a credit card, it is very possible that your purchases are still tracked - all it takes is cooperation between store and credit card company.

Not if you shop at a reasonable store. And even if that's not an option, I don't consider it "leaving money on the table", I consider it "buying privacy".

#93Watching criminal interrogations, I always think if I ever get caught wrongfully, my data can be my alibi. Is this incorrect?
It could also tie you to the scene of the crime if you're unlucky, so it depends if you're default paranoid or default trusting.

Why does it take cooperation with your credit card company? The supermarket can uniquely identify the card used for payment, even if they don't get the full credit card number due to PCI.

Edward Snowden revealed that u need to remove the battery on ur phone to make it "safe", turning it off doesn't do the trick. [Which u can't do anymore]. As another commenter says: leave the phone at home.
What about a Faraday bag?
A faraday bag works (but be sure to test it).
Be aware, though, that phones will increase their radio power and retry constantly when they aren't reaching a cell tower. If the increased battery drain is an issue, put your phone in airplane mode first.

That is a great option.

The clerks get penalized if they dont try to sign you up. They also have no insight or say in the use of your data. You might as well rant at a cloud about it.
Yes. Don't hassle the poor clerks. They aren't in charge of any of this stuff and certainly don't have the power to change it. Just say "no" and move on.
I normally wouldn't bother since I hate pushing my views on people (and I'm just there to buy food after all). But she asked me 3 times in a row and after 2 "no"s I decided I might as well try to explain why. It didn't make a difference and I left with a signup form I had no intention on filling out. Such are the downsides of being naturally polite. I guess I could just keep saying no and refuse to elaborate.

#98That the two biggest supermarket chains in the US are considering merger indicates that US antitrust enforcement is far too weak.
Albertsons is one of the biggest grocers, but it is tough to compare given that many retailers are expanding their grocery departments. Walmart probably moves the most groceries, and then Kroger, but Costco and Target are huge too.
It is a tough business to be in. 2% to 4% profit margins, and you have low cost German grocers entering the fray (Aldi and Lidl), stores with wider merchandise selections (Walmart, Target, and Costco), and then Amazon.
The bigger problem for old school grocery chains is the increasing divide in income/wealth, meaning more of the population is going to either the lowest cost retailers, and the remaining richer population is going to more upscale retailers.

> his is fine, but it's not really about tracking you, it's about tracking the habits of shoppers in aggregate, of which you are a participant. (Yes, having your real address to mail flyers is a bonus but not the end goal.) Like hell it is. This is an article about Target back in 2012, that identified a pregnant underage girl purely from her purchasing record. 11 years ago. https://www.forbes.com/sites/kashmirhill/20…

#100Sometimes it feels ridiculous how much OPSEC I need to employ to buy anything at the grocery store. I walk or bike to the store to not reveal a license plate. All radios and sensors on my handset are turned off. I wear a mask to thwart facial recognition cameras. I pay cash.
IME at Safeway if you don't use a "club card" you end up paying nearly double for many items. Are there ways around this?
Club card application information isn't usually validated, you can sign up for one with bogus information.
