I wrote a chrome extension to help with this. Clips all the coupons so you don't have to do individual searches. Has resulted in some wild surprise savings when shopping. www.throwlasso.com
Ha! I have the same thing as a bookmarklet for specific sites. It’s fun to watch it render the clicks.
This is interesting because I believe the two major supermarkets in Australia can create a duopoly in anti-competitive pricing by just employing price analysis AI algorithms on each side and the algorithms will likely end up cooperating to maximise profit. This can probably be done legally through publicly obtained prices and illegally by sharing supply cost or profit per product data. The result is likely to be simi…
The rationale is that if all prices are out there in the open, consumers will end up paying a higher price, as the actors (supermarkets) will end up pricing their stuff equally, at a point where everyone makes a maximum profit.
For years said supermarkets have employed "price hunters", which are just people that go to competitor stores and register the prices of everything.
Here in Norway you will oftentimes notice that supermarket A will have sale/rebates on certain items one week, then the next week or after supermarket B will have something similar, to attract customers.
Although might be hard to do with messy data.

For Germany, below the prices it says "some links may be sponsored", but it does not mark which ones. Is that even legal? Also there seem to be very few shops, are maybe all the links sponsored? Also idealo.de finds lower prices.
When I decided to put the text like that, I had looked at maybe 10-20 of the biggest price comparison websites across different countries because I of course want to make sure I respect all regulations that there are. I found that many of them don't even write anywhere that the links may be sponsored, and you have to go to the "about" page or similar to find this. I think that I actually go further than most of them…
I have been doing something similar for New Zealand since the start of the year with Playwright/Typescript dumping parquet files to cloud storage. I've just collecting the data I have not yet displayed it. Most of the work is getting around the reverse proxy services like Akamai and Cloudflare. At the time I wrote it I thought nobody else was doing but now I know of at least 3 start ups doing the same in NZ. It seems…
I built one called https://bbdeals.in/ for India. I mostly use it to buy just fruits and its saved me about 20% of sending. which is not bad in these hard times. Building crawlers and infra to support it tool not more than 20 hours.
We should mutualize scraping efforts, creating a sort of Wikipedia of scraped data. I bet a ton of people and cool applications would benefit from it.
Haha all we have to do is agree on the format, right?
The most important part is being able to consistently scrape every day or so for a long time. That isn't easy.
For my project (https://frankendash.com/), I also ran into issues with dynamically generated class names which change on every site update, so in the end I just went with saving a crop area from the website as an image and showing that.
We have been doing it for the Swedish market in more than 8 years. We have a website https://www.matspar.se/ , where the customer can browse all the products of all major online stores, compare the prices and add the products they want to buy in the cart. The customer can in the end of the journey compare the total price of that cart (including shipping fee) and export the cart to the store they desire to order it. I…
