Fun, useful project for tracking grocery prices
From 3 comments
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?
dgrin91 on HNYES! 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…

Prices only reflect one Chicago store; regional differences unknown
From 2 comments
Good catch. These prices are hard coded to my local store in Chicago. Soon I will add support for selecting your local store.
cmoog on HNYes, 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…

Hard to find items due to random ordering
From 1 comment
This is cool, but with the apparently random ordering it's just about impossible to find anything. Add sort buttons? A description of why this ordering is used?

Per-item price history graphs
From 3 comments
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).
xur17 on HNGiven 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).
ChuckMcM on HNI see the price change list, but is there a full history for all products? That would be really interesting to see.

A search filter would be helpful

Unit price tracking
From 2 comments
I wonder if this could encode unit price as well? It looks like the website will say /32 fl oz or /pound.
matthewbauer on HNMight be interesting to track their price per weight as package sizes commonly change these days ('shrinkflation')

Questions
How prices are collected: scraping or API
From 2 comments
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.
orange_county on HNWhere’d the prices come from? Scraping or an api?

Whether prices differ by store location
From 2 comments
This implies the prices are the same across all TJs stores - is that the case?
