Costco Warehouse Price & Inventory Checker
Did you know that Costco's mobile app actually lets you check warehouse-specific pricing and inventory? Most people don't -- and I don't blame them, because the experience is buried deep in their menus and the data isn't available on their website at all. I wanted that same data but in a format that didn't make me want to throw my phone.
So I built a quick web-based tool for it. Enter a search term and your zip code, and it finds the five nearest warehouses and returns real-time pricing and stock status for each. It's a simple Ajax-based frontend that queries Costco's inventory endpoints directly -- no scraping, no caching, just a much better UI for data that Costco already exposes through their app. Super handy for price-checking items across nearby locations before making a trip, or confirming that something is actually in stock at your preferred warehouse before you drive over there.
