think about it, home depot alone has 30,000 products in a store. and they have thousands of stores. incrementing and decrementing these items as they are sold with correct price, image, and descriptive text…sorry, not even google can handle that much data for even the top thirty retailers, let alone everyone. walmart reconciles their inventory once a day if i recall, and their IT infrastructure is more expensive and requires more staffing than google’s.

not ripping on google, just saying that real-time inventory aggregation for all major retailers is beyond the capabilities of our networks, hardware, and software.
