## Briefing
- ScrapingBee: A ScrapingBee blog post advocates for a cascade strategy that uses local extraction methods before resorting to a language model for zero-shot e-commerce scraping.

## Why it matters
The piece challenges the common reflex to throw an LLM at every scraping problem, highlighting the cost and latency of model calls. By promoting a cascade that first checks for embedded JSON and uses Scrapy, it offers a practical, cheaper alternative that could save significant time and money for practitioners dealing with e-commerce sites.

## Watch next
Will the cascade approach gain traction as a standard pattern in web scraping workflows?
