With Wishpicks Plus you set your own rule for each item: a drop percentage, a target price, or both. Whichever one is met first sends the alert. Free-plan tracking uses the default rule instead, and that one can't be changed.
Steps
Make sure you're on Plus and tracking the item. See "What is Wishpicks Plus, and what do you get?"
Open the item's tracking settings.
Set a drop percentage, a target price, or both. The percentage slider runs from 1% to 90%. The target price is the number you want to hear about, and you'll get an alert when the price reaches it or goes lower.
Save. Your rule takes effect at the next price check.
Good to know
Without a rule of your own, an alert fires at a drop of 9% or more. That's the default free tracking uses on partner stores, and changing it needs Plus.
Your rule only decides whether an item qualifies. The email still arrives on the normal grouped schedule. See "How do price-drop alerts work, and how often are prices checked?"
A drop on a sold-out item won't email you, and there are no restock alerts. See "Will Wishpicks tell me when a sold-out item is back in stock?"
