Efficient inventory management is crucial to prevent overstocking in saturated markets or missing opportunities in emerging ones. Analyzing product offers and sales trends helps in making informed inventory decisions.
Utilizing Amazon Product Offers
The Amazon Product Offers endpoint lists offers for a product, including price, seller, condition, and inventory details. This information is invaluable for assessing the supply side of the market.
