1. Know the usual price before the big day
Most “−40%” are computed against a list price inflated in the previous weeks. DeaLynx records prices daily and computes each product’s usual price over six months: the only honest reference.
Two days of Prime-only offers, a month and a half before Black Friday. It is often where holiday prices are lowest, but also where list prices are most generous. Our daily readings settle it.

Add them to your list now. On the day, you get an alert only if the price really drops below its usual level, not at every displayed “promo”.
The best offers are gone within hours. With a price threshold and, on the Sniper plan, a one-tap pre-filled cart, you are ready before everyone else.
Discounts measured against each product’s usual price, outlier readings excluded.












Amazon runs this event in early October over two days for Prime members. Exact dates are announced two to three weeks ahead; product pages often show “early” deals from late September.
On many products, October prices match Black Friday prices, with more stock. The seasonality shown on each DeaLynx product page tells, product by product, which month is historically cheapest.
Compare it with the product’s usual price over six months, not with the list price. On DeaLynx the deal score does that for you and the alert only fires if the drop is real.
