https://docs.paperless-ngx.com Nextcloud also has OCR. You can use a scanner with either. Avoid touching the receipts. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5453537/

hmm, I guess I have a weekend project now. And thanks for the heads up about the toxicity, I use to save them all but after the move I simply take a picture with my phone and throw them out. paperless doesn't seem to be my exact use case but hopefully after it does the OCR transformation it can allow you to make a csv file.

I'd look into a document scanner for ease of use. They even have ones that auto loads, so no more waiting around. With that said, if you purchase a scanner, it probably already has proprietary OCR, and they have auto feeding ones for many documents. I foolishly bought one not knowing auto feeding was an option. https://youtu.be/fi0ZhTFaW7w I bought a brother 2 sided one since it had Linux drivers.

Why is it funny prices rose as demand increases? That’s Econ 101 expected behavior

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).

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 mean, it's okay to leave it, (a) it's funny (b) it teaches them a lesson that attempts to track people are futile

This implies the prices are the same across all TJs stores - is that the case?

It is the case. It's kind of a famous quirk about their stores, that prices are identical nationwide.

I feel like Charles Shaw is an exception to that and cheaper in California?

iPhones dropped in price as demand increased. Demand isn't as important as marketing, and this is probably supply limited rather than demand.

iphones dropped in price?

TBH, people routinely overlook the other two factors, supply and underlying cost.

Sometimes increases in demand can both increase supply and decrease cost.

Modern tracking isn't bulletproof, but also not futile.

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…

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.

And who is the business consumer

Or... you could change it to something funnier, like "Pumpkin Body Butter"
