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?
cmoog · 2 years ago
Thanks! That's because it just started. I intend to keep the full history.

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 :)

Very cool!

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).

cmoog · 2 years ago
Agreed. Planning to add that next.

I see the price change list, but is there a full history for all products? That would be really interesting to see.
cmoog · 2 years ago
I plan to add that shortly. The data collection model supports it though.

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]

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.

I love this pattern of making tiny but powerful analysis tools with SQLite + a couple scripts.

And with Haskell and Nix at that!

This implies the prices are the same across all TJs stores - is that the case?
cmoog · 2 years ago
Good catch. These prices are hard coded to my local store in Chicago. Soon I will add support for selecting your local store.

Is this for one store or all stores? It's commendable that you posted your code, but a minimal README would be appreciated.

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.

cmoog · 2 years ago
Yes, you make a good point. Although I suspect there may be regional differences in price, I haven't yet run the diff on that. Should be simple enough for me to allow the user to select their regional store location.
