How do you find out what you bought using a sku number on your receipt?

To find out what you bought using a SKU number on your receipt, you can start by checking the retailer's website or app, as many have a search feature that allows you to enter the SKU for detailed product information. Alternatively, you can contact the retailer's customer service with the SKU number, and they can provide details about the item. If you have the original packaging, the SKU is often printed on it, which can also help identify the product.
