# scrape-giant
Small CLI pipeline for pulling purchase history from Giant and Costco, enriching line items, and building a reviewable cross-retailer purchase dataset.
CLI to pull purchase history from Giant and Costco websites and refine into a single product catalog for external analysis.
There is no one-shot runner yet. Today, you run the scripts step by step from the terminal.
Run each script step-by-step from the terminal.
## What It Does
- `scrape_giant.py`: download Giant orders and items
- `enrich_giant.py`: normalize Giant line items
- `scrape_costco.py`: download Costco orders and items
- `enrich_costco.py`: normalize Costco line items
- `build_purchases.py`: combine retailer outputs into one purchase table
- `review_products.py`: review unresolved product matches in the terminal

## Review Workflow
`review_products.py` is the manual cleanup step for unresolved or weakly unified items.
In the terminal, you can:
Run `review_products.py` to cleanup unresolved or weakly unified items:
- link an item to an existing canonical product
- create a new canonical product
- exclude an item
- skip it for later
Those decisions are saved and reused on later runs.
Decisions are saved and reused on later runs.
## Notes
- This project is designed around fragile retailer scraping flows, so the code favors explicit retailer-specific steps over heavy abstraction.
- `scrape_giant.py` and `scrape_costco.py` are meant to work as standalone acquisition scripts.
- `validate_cross_retailer_flow.py` is a proof/check script, not a required production step.

ok i ran a few. time to run some cleanups here - i'm wondering if we shouldn't be less aggressive with canonical names and encourage a better manual process to start.
1. auto-created canonical_names lack category, product_type - ok with filling these in manually in the catalog once the queue is empty
2. canonical_names feel too specific, e.g., "5DZ egg"
3. some canonical_names need consolidation, eg "LIME" and "LIME . / ." ; poss cleanup issue. there are 5 entries for ergg but but they are all regular large grade A white eggs, just different amounts in dozens.
Eggs are actually a great candidate for the kind of analysis we want to do - the pipeline should have caught and properly sorted these into size/qty:
```canonical_product_id canonical_name category product_type brand variant size_value size_unit pack_qty measure_type notes created_at updated_at
gcan_0e350505fd22 5DZ EGG / / KS each auto-linked via exact_name
gcan_47279a80f5f3 EGG 5 DOZ. BBS each auto-linked via exact_name
gcan_7d099130c1bf LRG WHITE EGG SB 30 count auto-linked via exact_upc
gcan_849c2817e667 GDA LRG WHITE EGG SB 18 count auto-linked via exact_upc
gcan_cb0c6c8cf480 LG EGG CONVENTIONAL 18 count count auto-linked via exact_name_size ```
4. Build costco mechanism for matching discount to line item.
1. Discounts appear as their own line items with a number like /123456, this matches the UPC of the discounted item
2. must be date-matched to the UPC
