If you see anyone online show the search results and pricing on Amazon, then try to replicate those search results and product price on a device that is totally partitioned from your viewing of the item/price elsewhere, you’re likely to find it is not possible. If you then go back to the original device and do the same, you’ll magically find the same product and lower price.
I noticed this on Walmarts website when asking chat GPT to find items for me. I was wondering why it was happening. Some of the price differences were extreme too.
