I live in Minnesota and use GrapheneOS with IronFox and uBlock, NoScript, and Privacy Badger. My desktop is Debian with librewolf and the same extensions.
I decided to check Spam prices at various Targets on both my phone and desktop. I don't typically shop at Target, though I do have an account with them but I haven't logged in in years. I was also not logged in for the testing.
I tried at my local Target and a few around the cities and got the same prices regardless of being on mobile or desktop. Only difference was between stores with prices ranging between $4.69 and $5.59.
I did not physically go anywhere different during this test, nor did I use a VPN, so that may have been why I was getting the same prices on both devices. I also really don't know how much Target actually knows about me other than my IP and that I block stuff.
Did you try checking while using data on your phone?
Using different network might give varying results.
I did but I didn't think about it until later so I didn't check as many stores. I tried it in a new incognito instance to avoid tracking cookies and etc, but I still got the same prices as with wifi. Although at that point they could have already identified me in some way, perhaps looking up only spam and blocking JS* makes me unique enough to identify.
* I did have to unblock the bare minimum needed to see the spam prices, so it's possible that could have allowed them to track me better as well.
Same, I'm also in a bunch of deals and sales channels.. Sometimes you can find great things. Most differences in pricing comes from franchise/corporate pricing and slight price variations.. The price of milk, eggs and soda, etc will be slightly different in NC and CA because of cost of living, taxes, and competition.
Now would I be surprised if mega corporations started a system where they varied price based on what they think they can get out of each person? No I wouldn't. Do I think they're looking at all that big data while twirling their mustaches and rubbing their hands together? Yeah I do, greedy little pricks. I just don't think we're there yet.
I recently learned about fingerprinting.

Interesting. I passed 2 out of 3. I have a unique headers problem. Using vanadium on GOS. Is this the place to download ironfox from ? https://gitlab.com/ironfox-oss/IronFox/-/releases
Yeah that's why I use what I use. I've checked that before and as long as I have JS disabled I'm at 1/1134 which is a pretty good score. Although sometimes you have to unblock sites to get them to work, so ¯\(ツ)/¯. Although at least webgl can be blocked separately.
It's a mixed bag really. Disabling JavaScript thwarts a lot of tracking efforts. But at the same time it puts you into a very small niche of users that, combined with other data points (user agent, IP location) makes you pretty fingerprintable.
Coming from a fellow JS Disabler, mind you.
