Compile Instamart Product PDF

I need a small utility that takes product names and their current prices from specific Instamart product pages, then merges everything into a single, neatly-formatted PDF. The flow is straightforward: I supply a list of Instamart URLs, your code grabs the name and price visible on each page, and it appends the information—cleanly styled, one product per page or section—into one combined document.

The solution can be a headless-browser script (Python + Selenium, Puppeteer, or a similar approach) or a lightweight extension—anything that reliably captures live data and auto-generates the PDF without manual copy-paste. An easy way for me to add or remove URLs later is important, so a simple input file or command-line argument works well.

Deliverables:
• Source code with clear setup instructions
• A quick demo run showing multiple products compiled into one PDF
• Brief read-me explaining how to update the product list and regenerate the document

Accuracy of the captured price text and a clean, readable PDF layout are the key acceptance points.
