Some day in the near future, the marketing department will wonder why so many people were curious about all of their products after browsing Organic Ground Beef[0] [0]: https://github.com/cmoog/traderjoes/blob/ea2da58a84d3a04e28f...

Haha true. I should fix that.

I'd also change it to `Referer`, as that is what Chrome seems to be using.

And referrer is set twice!

Interesting! I’ve always held on to my grocery receipts for the last 8 years. I took pictures of them but when I moved a box got water damaged so now I only have like the last 3ish years. Is there any open source software that I can use to transfer these receipts into a useful csv? I have an idea for a few interesting data visualizations as I’d often buy the same things every week. Grocery bill went from like $70 to…

ChatGPT Vision will do well with this kind of OCR stuff. Just give it the header and a few example rows to get back consistently formatted output.

Or use JSON mode with the API.

I'd love it if Apple (since they appear not to sell data) would provide an anonymized receipt analysis service like this. Huge user base right off the bat.

I wish there was just a standardized receipt sending format that would send your receipt to your pay app once you tap to pay something.

Of course, I can only imagine this coming to fruition if it is packed to the brim with tracking and 3rd party dissemination.

Earlier quoted context omitted.

Except for a the obvious counter examples. Like food in general very in demand and very cheap. Housing very in demand but very expensive. So it’s really more about who decides the prices than what.

Econ 101 explains those counter examples as well: Food has high demand but lots of competition and easy substitution (rice expensive? buy pasta). Housing supply is limited (by location but often artificially via regulation) and substitution is difficult (have to move).

How many recessions has "Econ 101" predicted? Economics is a "soft science", on the same tier as psychology which people love to ridicule. Understanding how rational actors behave in a microeconomic sense doesn't help you when you're talking about irrational actors in the macroeconomic sense

Given that these prices are going into a database, I was hoping that you could click on an item and get its pricing over time (not a referral link to the Trade Joes web site).

Looks like they're just straight up links, and not referral links. Pretty sure nobody is earning a commission when someone clicks them.

I can assure you I am not earning a commission :)
