Amazon price match deals if product is from amazon itself

quote—Have you ever bought something on Amazon only to see the price drop shortly after your purchase? Most likely, it’s happened to just about everyone who buys something on Amazon. So many in fact, that Amazon had to change its policy regarding price changes from 30 days down to 7 days. So right now if the price changes, you can only get the refund if it’s within one week of your purchase date.#Note: This Amazon price-change refund policy only applies to items shipped and sold by Amazon. If you’re buying from a different vendor who is selling on Amazon, you’ll just be directed to contact that vendor if the price dropped./—end_of_quote- source link

Also a reminder, as previously mentioned, some citi visas have a benefit that you can register a product for automated price comparison with hundreds of online sites for a better price, if one is found, I think you're given a refund for the difference, iirc.   I think it's called price rewind or something like that
