This brings me back...the year was 1999 and I had an idea for a comparison shopping engine. Online was easy but I wanted to include brick and mortar stores. I went door to door around UCLA asking stores if they could provide a real-time XML feed of their inventory. Most had proprietary POS systems that didn't even connect to the internet, some had export to Excel, but you'd have to manually send it out.
I wonder how much different it is now?
