"The focus on matching Walmart on price also created some issues, like when Amazon's pricing tool would repeatedly lower the price on an item to match its competitor, leading to what insiders dubbed a death spiral. Amazon created a specialized team to try to determine how and when to decide that its pricing tool should pull back and no longer match Walmarts lowest price on a given item, but instead match the next-lowest price from a competitor. The initiative was called Project Nessie. In the end, the program was scrapped when it was determined that the tool did not lead to more profitable outcomes, according to Amazon spokesperson Jordan Deagle."
