## Idea

Perishable Delivery Shelf-Life Agreement
Set minimum remaining shelf-life requirements before ordering perishable groceries, then verify delivery photos against them and generate refund-ready evidence when an item falls short.

## Product concept

People who buy milk, yogurt, meat, and ready-to-eat food online can set a minimum remaining shelf life for each category—for example, at least seven days for milk, five for yogurt, and three for refrigerated meat. At checkout, the product turns those preferences into short, clear picking instructions linked to the relevant order lines. After delivery, the user photographs the front of the package and the date area. The system identifies the product name and production or expiration date, then compares them with the order and saved requirements. It clearly shows which items meet the agreement, which fall short on remaining days, and whether a date photo is incomplete. When an item does not meet the requirement, the page automatically compiles the order number, order line, date close-up, and original picking instruction. After reviewing it, the user can copy the explanation needed for retailer support or a refund form. Deadlines for returns, partial refunds, or replacements appear on the same card, so users do not have to hunt for the original packaging or order record days later. The first version would support refrigerated and short-shelf-life products with relatively standardized date formats. It does not assess whether food has spoiled or replace cold-chain safety testing. Its role is to align a pre-purchase shelf-life requirement with packaging evidence at delivery, creating a clear record of whether near-expiry goods met the agreement.

## Why now (backed by facts)

On July 20, an r/Frugal user said milk they received had only 2–3 days remaining and that they had seen bottled tea 10 days past its expiration date. As shoppers begin comparing dates by store and product category, there is still no unified record connecting order requirements with delivery evidence.

## Direction (model inference, not independently verified)

Target user: The core user is a household grocery shopper who orders milk, yogurt, and refrigerated meat online every week. They often notice shorter-than-expected dates only while putting groceries away, when the order is still accessible and the packaging has not yet been discarded—the best time to verify and document the issue. For people planning meals, caring for children, or trying to reduce store trips, remaining shelf life directly affects the week ahead.

Minimal entry point: Start as an iPhone delivery-verification tool rather than taking over checkout. Users can forward an order screenshot or add order lines manually. The capture flow separately guides them to photograph the package front and date area. Apple Vision can recognize text and barcodes on device. Date parsing should cover only unambiguous month-day-year combinations, and low-confidence results must be confirmed by the user. The system calculates remaining days from the delivery date and creates an editable evidence summary. The first release should match refund wording for only one or two retail platforms and should not submit disputes on the user’s behalf.

The strongest case against: Date-recognition errors could classify an acceptable item as near expiry, trigger unnecessary refund requests, and undermine trust in the tool. Package dates may refer to sell-by, best-by, use-by, or freeze-by dates, and their meanings are not standardized. Reflective film, worn inkjet printing, and curved containers can further reduce recognition accuracy. Order item names may also fail to match abbreviated package names. To reduce risk, every check must show the original image, date type, and confidence cue. If users still need to make frequent manual corrections, the convenience of taking a photo disappears. Retailers may not recognize a customer-defined shelf-life threshold, so an evidence pack can make communication more efficient but cannot guarantee a refund.

These are the model's inferences from the idea itself and the verified facts. Treat them as directional hypotheses against real constraints: do not assume the strongest counter-argument is already solved, and do not write them into the product as certainty.

## Punching above weight (model inference)

Enter through money-saving communities that regularly use grocery delivery. Publish a printable shelf-life preference chart by product category with a link to photo verification. Build retailer-specific after-sales templates to capture searches such as “what to do when near-expiry groceries arrive.” Invite anonymous submissions of hard-to-read date photos to build a packaging-style test set over time. Case-study exchanges with newsletters about household budgeting, meal prep, and waste reduction would reach users closer to the moment the problem occurs than broad App Store advertising.

## Competitors & gaps (model inference)

- Instacart order issue reporting: Instacart lets customers report expired, damaged, or spoiled items from an order. They can select the affected item and request a refund or account credit, and self-service reports must be made within three days of delivery or pickup. This is post-issue support within a single platform. Its public help pages do not offer a way to set a minimum remaining shelf-life requirement before ordering or attach that requirement to each order line. Customers must still read package dates themselves and decide whether a report is worthwhile. The opportunity is to save acceptance criteria first, then verify them against delivery photos. An evidence pack could also support a retailer’s own customer service rather than being limited to one platform.

## How it makes money (model inference)

Monthly subscription. The free tier includes a limited set of product rules and manual checks; the subscription adds household sharing, more order history, evidence-pack exports, and deadline reminders.

Trigger Web Trend observation: u/Historical-Voice2944（r/Frugal） — Has anyone else found Walmart (and Sam's Club) to no longer be a frugal choice?

This is one observation bounded by its publication and capture times. It is not evidence of market size or a broad trend and only explains “why now.”

## Deliverables

- Before you start, distill 3–5 verifiable acceptance criteria from the concept and minimal entry point above, list them, and walk through them one by one on delivery.
- Ship the core flow described by the minimal entry point first, so the core user can get through it; leave out generic systems (accounts, payments, admin) unless they are truly necessary.
- Do not show unverified market numbers in the UI or API.
- Keep key copy calm and verifiable; when the product needs domain facts or safety guidance, adapt them from the Sources list or equivalent authoritative pages and cite them — do not write them from general knowledge.
- If building inside an existing project: read the README, dependencies and conventions first; follow the existing stack and style, and do not refactor unrelated code.
- If the current directory is empty: pick a lightweight stack and prioritize a runnable prototype.
- When done, explain what changed, how to run it, and how to verify it.
- Ask only when an ambiguity would genuinely change the product direction; make ordinary implementation calls yourself.
