Amazon often teases its lightning deals in advance. If you visit the Prime Early Access Sale 2022 webpage, for example, you may see a carousel of Lightning Deals. Keep scrolling through those deals, and you’ll soon hit products that are on deck but haven’t yet started as deals. If you find something in those upcoming Lightning Deals you’d like to buy, that’s the time to do historical price-checking. Then when the product goes on sale, you’ll know right away if Amazon’s limited-time price is worth it.
