Here is how to search for products sold and shipped by Amazon. This becomes important because certain promotions (e.g. Amex 40% off up to $60) require the items to be sold and shipped by Amazon in order to get the discount.
Summary: To find Amazon products eligible for specific discounts, replace the “&” in the search result URL with “&rh=p_6%3AATVPDKIKX0DER” after searching for the desired product.
Detailed Steps:
1. Search for the product e.g. “jumpstart battery pack”
2. Step 2: Look for the “&” in the URL of the search result:
https://www.amazon.com/s?k=jumpstart+battery+pack&ref=nb_sb_noss
3. Replace the “&” with this: &rh=p_6%3AATVPDKIKX0DER and click Enter:
https://www.amazon.com/s?k=jumpstart+battery+pack&rh=p_6%3AATVPDKIKX0DER
