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.
During Prime Day, Amazon runs countless lightning deals. Some are real, others fall back to a price seen two months earlier. Our daily readings make the difference.

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 usually announces Prime Day in July, over two to four days, for Prime members only. Exact dates are confirmed a few weeks ahead.
Often, but not always. Amazon’s reference price can be one rarely charged. DeaLynx compares each offer with the usual price recorded over six months and discards outlier readings.
Track your products before the event with a price threshold. On the Sniper plan, the alert opens the pre-filled Amazon cart: one tap and it is ordered before it sells out.
