+## Ebay Scraper (Storage)
+
+A truly awful *very* LLM generated scraping tool used to help me find good deals on ebay for Storage. Again, this is LLM generated, basically vibe coded, so the code quality has virtually zero oversight. The generation of this was done using Gemini 2.5 Pro, see the [conversation](https://g.co/gemini/share/3d80b96e42e9).
