💡 Why Amazon sellers and brands use this scraper

On Amazon, the Buy Box drives the overwhelming majority of sales — and it changes constantly as sellers compete on price, fulfillment, and stock. If you sell on Amazon, or protect a brand on Amazon, you need to answer these questions continuously:

• Who currently owns the Buy Box on my listing, and at what price?
• Who are the other sellers competing on this ASIN, and how are they priced?
• Did a new (or unauthorized) seller just appear on my product?
• Is someone undercutting my price or breaking MAP?
• Is the offer fulfilled by Amazon (FBA) or by the merchant (FBM)?

This scraper answers all of them — per ASIN, across every major marketplace, on whatever schedule you choose. Run it once for a snapshot, or schedule it to power a live repricing and brand-protection workflow.
