If you don't mind sharing, how do you find their API? I don't understand graphql that well and I've been trying to play with https://www.traderjoes.com/api/graphql to no avail. Cool project, github star achieved.

Just browse the website and look at the requests it makes to their API.

This is shredding close to HNs "please no political battle", but I'll try to take this as neutral as possible.

You are suggesting these are stores people should avoid for labor-unfriendly practices. Assuming that people are aligned with you on that value set, I don't think a sarcastic comment without actual recommendations, on a post about a tangentially related project, is going to move any needles.

And so, assuming the mods let us live: What are your recommended alternatives to TJs? TJs is, for better a worse, one of the few grocery store options with both decent quality and not entirely ludicrous prices. This project makes it even more enticing, because you can finally look up prices directly and see price history.

If there's another store that offers all that, I think a lot of people would be interested, independent of "why".

Earlier quoted context omitted.

> Most people don't buy pasta when rice is expensive. They would if rice prices went through the roof, which they won't because people who sell rice are not stupid. Econ 101 certainly explains why you can actually buy gluten free products now (supply for demand) and why gluten free products are usually more expensive (niche market). My ECON 101 prof talked about the limitations of models and theories based on assumpt…

No, they're geniuses because they're subsidized and will always be profitable. They lowered prices by taking it from your taxes. Throw in subsidies like how Clinton ruined Jamaican rice with protectionism and your supply demand and price are no longer rational. https://www.texasgateway.org/resource/201-protectionism-indi... Econ 101 ignores subsidies which account for 100% of the big 3 crops and more like rice, and i…

I don’t know where you took Econ 101 but mine definitely covered how things like subsidies and protectionism perversely impact market forces. You’re just blaming economists for bad policies at this point.

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.

Sorry can't edit it now but you are correct and I wasn't thinking "that" kind of referral :-). Easy to see that interpretation though, will have to remind myself to use "links that reference the product".

FWIW cmoog, I think it is pretty cool. I've always felt that good surveillance on retail prices with specific product information (like weight/servings) would be a solid data set for economists and people like me to understand "real" inflation, "greed" inflation, and general product pricing trends.

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

I think there are enough grocery apps that it is better to show price data than not. Though I'm certainly baising that off how I shop rather than a general economics / game theory POV.

I regularly use the Ralphs app to cross shop while I'm at Trader Joes. They are only 2 minutes walking apart, so I normally start at TJs. However, sometimes I end up at Ralphs first and now having this data it could lead to an unplanned trip to TJs to save a few bucks.
