Grocery prices crawler tô show the nearest and cheapest buy

Confidence
Engagement
Net use signal
Net buy signal

Idea type: Freemium

People love using similar products but resist paying. You’ll need to either find who will pay or create additional value that’s worth paying for.

Should You Build It?

Build but think about differentiation and monetization.


Your are here

Your idea for a grocery price crawler aligns with the 'Freemium' category, meaning many people find value in similar tools but are hesitant to pay. With 16 similar products already out there, the market is competitive, so differentiation is key. The high engagement (average of 12 comments per product) suggests people are interested in this type of service, but there are no net use or buy signals, indicating a strong resistance to paying. PennyMeal, Many Penny, and Price Prowler, among others, demonstrate the demand for finding cheap ingredients and comparing prices, but you'll need to identify a way to offer unique value or cater to a specific niche to stand out in this crowded space. Finding the right monetization strategy will be crucial for long-term success.

Recommendations

  1. First, focus on identifying your ideal user and the specific problem they face when grocery shopping. Is it time savings, budget constraints, or access to specific items? Understanding their needs will help you tailor your crawler and its features.
  2. Analyze the criticism from similar products. Many Penny users want more categories, while The Price Prowler needs better filtering and sorting (by reviews, delivery time). Address these pain points to offer a superior user experience. If you could add a price drop alert (similarly to PriceChecker) this could be a great feature.
  3. Consider adding unique features to differentiate your crawler. Could you incorporate nutritional information, recipe suggestions based on price, or integration with meal planning apps? Explore AI-powered deal finding or even a browser extension, however, make sure that all the affiliate tags are disclosed (according to the negative feedback from 'I Made an AI Deals Finder to Help You Find the Best Deals on Products')
  4. Explore various monetization strategies beyond direct payment. Could you partner with local grocery stores for sponsored listings, offer premium features like advanced filtering or price tracking history, or create a B2B solution for restaurants and food businesses? Also consider the Daily price tracking for Trader Joe's example: what if you could create a public API?
  5. Start with a Minimum Viable Product (MVP) focusing on core functionality and gather user feedback early and often. Iterate based on their needs and preferences to build a product that truly solves their grocery shopping problems.
  6. Given the 'Freemium' category context, identify which users get the most value from the free version of your crawler. Then, develop premium features that cater specifically to their needs, enticing them to upgrade.
  7. Think about targeting teams or groups, such as families or small businesses, rather than individuals. This could open up opportunities for charging based on the number of users or features required.
  8. Consider offering personalized help or consulting services related to grocery shopping, meal planning, or budgeting. This could be a valuable add-on for users who need extra support.
  9. Test different pricing approaches with small groups of users to determine what works best. Experiment with subscription models, one-time purchases, or even a combination of both.

Questions

  1. Given the lack of 'buy' signals in similar products, what specific value proposition will convince users to pay for your grocery price crawler? How can you create a sense of exclusivity or necessity around your premium features?
  2. How will you ensure the accuracy and timeliness of your price data, and what measures will you take to address potential errors or discrepancies? How do you avoid legal issues, similarly to the Daily price tracking for Trader Joe's example?
  3. Considering the competitive landscape, what is your long-term vision for the grocery price crawler? How will you continue to innovate and adapt to changing market conditions and user needs?

The y-axis captures the strength of the signal, i.e. how many people commented and how does this rank against other products in this category. The maximum is +1, which means these products were the most liked, upvoted and talked about launches recently. The minimum is 0, meaning zero engagement or feedback was received.

The sizes of the product dots are determined by the relevance to your idea, where 10 is the maximum.

The Price Prowler - Get instant access to the best prices from top retailers

Find the cheapest prices online. Search by the pound, ounce, gallon, quart, and more!

Price Prowler is a helpful tool for finding the best deals and cheapest prices, simplifying shopping, and saving money by comparing prices. Several users have highlighted its utility in aiding budgeting. However, there's a need for improved filtering options within the tool.

The main criticism is the need for sorting options, specifically by user reviews and delivery time. This functionality is currently lacking, hindering users' ability to effectively filter and prioritize products based on these criteria.

Daily price tracking for Trader Joe's

08 Feb 2024 Productivity

Source code here: https://github.com/cmoog/traderjoes

Comments reflect a mix of technical discussions about HTTP 'referer' misspellings, suggestions for product name changes, and discussions on receipt OCR conversion. Users express interest in tracking grocery prices, particularly Trader Joe's, with mentions of a public API and price consistency across stores. There's debate on economic principles, such as supply and demand, and the rationality of consumers. Some users request features like price history graphs and search filters, while others discuss the value of products and regional price variations. Concerns about labor practices and legal issues, like a potential cease and desist from Trader Joe's, are also raised.

Users criticized the product for persistent spelling mistakes, lack of clarity in target audience and receipt information, concerns over tracking and data privacy, manual updates, and the need for better organization and automation. Criticisms also focused on economic assumptions, price tracking accuracy, and the lack of comprehensive price history. Users noted regional variations in product quality and pricing, and legal restrictions affecting product availability. The feedback suggests a need for clearer communication, improved functionality, and consideration of user privacy and real-world economic factors.

I scraped 300M products to build a real-time price comparison extension

Hey HN,I built a real-time product price comparison chrome extension.While you're shopping, it looks for products that are similar/same to the ones you're viewing and searches for their prices in real time.You have to be on a product page (which has a product schema) for this to work.Once similar products are identified, the chrome extension will pop up a list to show you a comparison of where you can get the same item for cheaper.Here's what it looks like: https://imgur.com/a/rmQX7krAlso, once you reach the checkout, if we have coupons and we support that merchant, we'll also auto apply the coupon codes for you as well.I'd love any feedback!Website: https://www.dealdrop.com

Users noted that the product listing includes brands and prices but lacks purchase locations. Additionally, there are concerns about potential FTC rule violations due to the absence of affiliate tag disclosures.

The main criticisms are the lack of locations to buy American cheese and the failure to disclose the use of affiliate tags.
