How are they getting the prices for these? Is this run by Trader Joe’s? I hope someone isn’t manually updating these. Also won’t prices differ by location? So many questions.

Discussion of regional price differences in other comments.

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…

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/

didn't see anything specifically receipt oriented but found a little blurb here that mentions receipts almost tangentially https://docs.paperless-ngx.com/usage/#basic-searching

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

Good catch. These prices are hard coded to my local store in Chicago. Soon I will add support for selecting your local store.

I am seeing comments that their prices are the same nationwide? Less work for you if true :)

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.

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 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.
