Grocery and delivery pricing looks like an ordinary ecommerce scraping problem and behaves like a local one. There is no single price for an item: it depends on which store, which platform, which address and which moment.
This guide covers what that means for a collection design, why fee structures matter more than list prices, the app-first obstacle, and where the limits are.
Key Facts
- There is no national price on these platforms. Catalogue, availability and fees resolve to a delivery address, so a dataset without an address is not comparable to anything.
- The same store differs between platforms. Menu prices are frequently marked up per platform, so a cross-platform comparison measures markup as much as price.
- Fees are where the real cost hides: service, delivery, small-order and surge fees can exceed the basket difference you were measuring.
- The apps are the primary surface, and the web versions are often reduced, which limits what public collection can see.
- Terms restrict automated access on every major platform, which makes scope and rate the first design decision, not the last.
Why is address the deciding variable?
Food delivery data scraping stands or falls on this: the platforms resolve everything downstream of the address. We call it the 4-part locality model.
| Variable | What the address decides | Effect on a dataset |
|---|---|---|
| 1. Store set | Which stores deliver to you at all | Different addresses produce different catalogues entirely |
| 2. Prices | Store-level and zone-level pricing | The same SKU carries different figures a few kilometres apart |
| 3. Availability | Live stock for that store | Out-of-stock is a price signal and is usually discarded |
| 4. Fees | Delivery distance, minimums, surge | Total cost moves independently of item price |
The practical consequence: every record needs the address or zone it was collected for, stored alongside it. A price series that silently mixes zones produces variance that looks like market movement and is really geography. City or ZIP-level exits are what make that reproducible, and DataImpulse residential supports that targeting at $1 per GB across 195 countries.
What makes cross-platform comparison misleading?
Markup. Restaurants and stores frequently list higher prices on delivery platforms than in store, and the size of that markup differs per platform. Comparing two platforms on item price therefore measures their commercial arrangements, not the underlying product cost.
Fees compound it. Service fees are usually a percentage, delivery fees vary by distance and time, small-basket surcharges appear below a threshold, and surge pricing moves through the day. A basket that looks ten percent cheaper on one platform can cost more at checkout.
The only comparison worth reporting is total cost at checkout for a defined basket, at a defined address, at a defined time. Anything less specific invites a conclusion the data does not support.
What can actually be collected?
| Source | Use this when | Avoid when |
|---|---|---|
| Platform web storefront | Data appears there and terms permit the access pattern | The web version is a reduced catalogue |
| Retailer’s own site | You want shelf price without platform markup | You are studying delivery economics specifically |
| Official or partner APIs | One exists for your relationship | Never scrape around a documented feed |
| Manual or panel sampling | Coverage matters less than accuracy | You need thousands of daily observations |
The app-first reality limits row one. These businesses invest in their apps, and the web surface is frequently a subset. That caps what public collection can see, and a dataset should state that limit rather than imply completeness.
What are the rules and limits?
Terms restrict automated access on every major delivery platform. That makes the scope decision the first one: a small, slow, clearly-bounded collection for price research is a different proposition from continuous full-catalogue extraction, and they are not treated the same.
Be gentle with rate. These are consumer platforms with real capacity limits, and aggressive collection is both visible and unkind.
Do not collect personal data. Reviews, courier names and order histories are personal data; a price dataset does not need them.
Timestamp everything. Surge pricing and promotions mean a price without a time is not a fact. General information rather than legal advice: see is web scraping legal.
Frequently Asked Questions
Why do delivery prices differ for the same item?
Because the platform resolves store set, prices, availability and fees against the delivery address. Two addresses a few kilometres apart can see different stores, different prices and different fee structures for the same product.
Can I compare prices across delivery platforms?
Only at checkout total for a defined basket, address and time. Item prices are frequently marked up per platform by different amounts, so comparing list prices measures commercial arrangements rather than product cost.
Do I need city-level proxies for this?
Yes, if the data is meant to describe a market. A national exit gives you one arbitrary zone’s catalogue, and mixing zones in one series produces variance that looks like market movement but is geography.
Is the data available on the web or only in apps?
Both, unevenly. These platforms are app-first and the web storefront is often a reduced catalogue, which caps what public collection can see. A dataset should state that limit rather than imply full coverage.
Is scraping delivery platforms allowed?
Their terms restrict automated access, so scope and rate are the first design decisions. Retailers’ own sites are frequently a better source for shelf prices, and official or partner feeds should always be preferred where a relationship exists. General information, not legal advice.
Collect at the address, not at the country
Delivery catalogues and fees resolve to an address, so a country-level exit gives you one arbitrary zone. DataImpulse residential supports country, city and ZIP targeting at $1 per GB across 195 countries. Create an account.
