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]<p>[0]: <a href="https:&#x2F;&#x2F;github.com&#x2F;cmoog&#x2F;traderjoes&#x2F;blob&#x2F;ea2da58a84d3a04e28f36270d1ac0e98a5473be7&#x2F;Prices.hs#L110">https:&#x2F;&#x2F;github.com&#x2F;cmoog&#x2F;traderjoes&#x2F;blob&#x2F;ea2da58a84d3a04e28f...</a>

Interesting!<p>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.<p>Is there any open source software that I can use to transfer these receipts into a useful csv?<p>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 $150 with not much changes from what I can tell.<p>Would be cool to put it out in the public.

At the current price of $0.01 for 9ft, you could buy enough Trader Joe&#x27;s Felted Wool Garland to wrap around the earth for just $146,000. Not bad!

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).

Open food fact recently launched Open Prices (<a href="https:&#x2F;&#x2F;prices.openfoodfacts.org&#x2F;" rel="nofollow">https:&#x2F;&#x2F;prices.openfoodfacts.org&#x2F;</a>). It&#x27;s currently crowd-sourced instead of an automated crawling, but prices are localized in space and time which could lead to intersting results. This will lead to an open database of food product prices.

Pleasantly surprised to see about as many price reductions as price increases. Also funny that they marked up the price of roses ahead of Valentine&#x27;s Day!

surprised to see trader joe&#x27;s exposes prices via graphql: <a href="https:&#x2F;&#x2F;github.com&#x2F;cmoog&#x2F;traderjoes&#x2F;blob&#x2F;54588336f3b7a4ce23c66afc4272349eadaccb8f&#x2F;Prices.hs#L87">https:&#x2F;&#x2F;github.com&#x2F;cmoog&#x2F;traderjoes&#x2F;blob&#x2F;54588336f3b7a4ce23c...</a><p>one of the few notable production gql users?

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

Pretty sure TJ&#x27;s has also given us shrinkflation. I suspect the almond-butter bottles have gotten smaller (but same price).
rnadomvirlabeover 1 year ago
Is this for one store or all stores? It&#x27;s commendable that you posted your code, but a minimal README would be appreciated.<p>Looking through your code, I see that the default store is Chicago South Loop (701). This would be helpful information to include on the website displaying the results.

As of right now, it costs $9,039.55 to buy one of everything on the list.

Were you aware of, or tempted by <a href="https:&#x2F;&#x2F;datasette.io&#x2F;" rel="nofollow">https:&#x2F;&#x2F;datasette.io&#x2F;</a> for creating your solution?

This is very fun, I like it. The price history only goes back a few days, is that because this just started or do you only keep a few days of history?

Very cool!<p>It would be neat to be able to click on a product and see a price history graph as well (since it seems like you should have this data your db).

The $1.99 Dijon mustard is the best bang for the buck for Dijon on the US market. Maybe even cheaper than in France.<p>But where are the cornichons?

If you don&#x27;t mind sharing, how do you find their API? I don&#x27;t understand graphql that well and I&#x27;ve been trying to play with <a href="https:&#x2F;&#x2F;www.traderjoes.com&#x2F;api&#x2F;graphql" rel="nofollow">https:&#x2F;&#x2F;www.traderjoes.com&#x2F;api&#x2F;graphql</a> to no avail. Cool project, github star achieved.

Might be interesting to track their price per weight as package sizes commonly change these days (&#x27;shrinkflation&#x27;)

The founder of &quot;Trader Joe&#x27;s&quot; Joe Coulombe, wrote a memoir. One of the better business books you&#x27;ll read:<p><a href="https:&#x2F;&#x2F;www.harpercollinsleadership.com&#x2F;9781400225422&#x2F;becoming-trader-joe&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.harpercollinsleadership.com&#x2F;9781400225422&#x2F;becomi...</a>

I wonder if this could encode unit price as well? It looks like the website will say &#x2F;32 fl oz or &#x2F;pound.

I see the price change list, but is there a full history for all products? That would be really interesting to see.

Trader Joe&#x27;s sells liquor?? Guess I wouldn&#x27;t know living in Texas. That&#x27;s surprised me though.

I would love a directional arrow in the table to indicate prices from day to day.
muhammadusmanover 1 year ago
YES! thank you for doing this, I have been curious about some of the stuff I buy often and I felt like over the last year or two, things have climbed in prices a lot compared to the normal inflation price hikes.
faramarzover 1 year ago
Ha! The uptrend towards Valentine’s Day - florals up from $9.99 to $14.99!<p>Really cool, and gives you POV like you’d get with Uber Surge.<p>Is this how retailers hedge and make up for losses elsewhere?<p>I wish we could also know tracked wholesale price.
ctrlGsysopover 1 year ago
Nice project.<p>Open nodes at stores could help BLS &amp; commercial orgs doing regular price data gathering. I work on supplier pricing dynamics and for commoditized products freeing your pricing data is powerful.
dtgriscomover 1 year ago
This is cool, but with the apparently random ordering it&#x27;s just about impossible to find anything. Add sort buttons? A description of why this ordering is used?

Setup an alert system so I can be alerted when seasonal items are in stock. I need more lebkuchen.

Prices of two dozen roses went up by 50% just in time for St. Valentine&#x27;s Day.

Would be much more interested if that data had a date associated with each row...

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

Honestly it&#x27;s wild that they publish live prices online. Can they be _that_ confident that they&#x27;re under-cutting competitors all the time?

Where’d the prices come from? Scraping or an api?

it would be nice to round all the 0.99 to 1.00 so its easier to see how much things really cost

I hope not, but this is likely to get C&amp;D&#x27;d by the famously secretive TJs.

I&#x27;ve decided to stop patronizing Trader Joe&#x27;s after they argued that the NLRB is unconstitutional.
