The Deal Edit
Setting up a price alert is the easy part — the harder question is which tool actually tracks the thing you're buying. Amazon-only tools miss everything else you shop, and general browser extensions often miss the deep price history that tells you whether a "sale" is real. Here's how to match the tool to what you're actually buying.
If you mostly shop Amazon
Amazon-specific trackers like CamelCamelCamel and Keepa exist for one reason: Amazon's prices move constantly, sometimes multiple times a day, and neither tool requires anything installed to check a product's price history at a glance. Paste a product link in and you'll see months or years of price swings charted out, which makes it obvious whether today's price is actually low or just average with a "limited time" label stuck on it.
If you shop all over the place
For everything outside Amazon, a browser extension that runs automatically at checkout is more useful than a site-specific tool, since it doesn't require you to remember to check anything. These extensions typically search for a lower price elsewhere and try to auto-apply coupon codes at checkout — useful as a last-second check, but worth remembering they're reactive. They tell you if a better price exists somewhere else right now; they generally don't tell you whether the price in front of you is high or low compared to where it's been over the last few months.
If you're buying something big and infrequent
Furniture, mattresses, appliances, and other big-ticket items don't go on sale often enough for day-to-day tracking tools to be useful — you might buy one every five to ten years. For these, a manual approach works better than an automated one: check a retailer's own price history where it's shown, search "[item] price history" before a big purchase, and if you can, wait for a named sale event in that category rather than trying to time an individual product.
If you're prone to impulse buying
A price alert can double as a cooling-off mechanic, not just a savings tool. Instead of buying the moment you see something, set an alert at your target price and close the tab. If it hits that price, you'll get a notification and still get to decide then whether you actually want it — which filters out a lot of purchases that only felt urgent in the moment they showed up in your feed.
What we do differently here
Every deal on this site already has 90 days of price history checked before it's allowed to call itself a discount — the tracking work these tools do for you individually is baked into how a deal earns a spot here in the first place. If you'd rather skip setting up your own tracking, today's live deals are already sorted by category and verified against real price history, not a retailer's claimed "was" price.
