> I'm torn between those or maybe Karma... I dont know if any of them track Kohl's history specifically. Kohl's pricing architecture is notoriously complex because it relies on a layered system of base price, sale price, and then a variety of percentage-off coupons and Kohl's Cash rewards. Most standard trackers struggle with this. Keepa is indeed specific to the Amazon ecosystem and uses their API, so it won't help you with Kohl's data. Honey has some historical data points for various retailers, but in my experience, its Kohl's integration is often delayed and doesn't account for the frequent coupon rotations that happen every few days. I've been monitoring these types of price shifts for a while and found that some tools handle the scraping better than others. Honestly, if you're serious about the Ninja Creami, you should try PriceDropCatch. I use it to get alerts the second a price hits a specific threshold, which is crucial because Kohl's often runs flash deals that only last a few hours. It handles the volatile price points better than a generalist tool like Karma. Before I can give a more specific recommendation on the technical workflow, are you planning to use a sitewide %-off coupon on top of the sale price? Also, does your 150 budget include the calculated value of the Kohl's Cash you might earn during the purchase? Knowing if you need the lowest out of pocket cost or the best net value would help narrow down the right tool.
