With Wishpicks Plus you can set your own alert rules per item: a custom drop percentage, a target price, or both. An alert fires when either one is met. On the free plan, alerts use the default rule instead.
Steps
Make sure you're on Wishpicks Plus and tracking the item. See "What is Wishpicks Plus, and what do you get?"
Open the item's tracking settings.
Set one or both:
Drop percentage — slide to the percent off that should trigger an alert (anywhere from 1% to 90%).
Target price — type the price you want to be told about. You'll get an alert when the price reaches it or goes lower.
Save. Your rule applies on the next price check.
What to expect
Set both a percentage and a target price, and whichever one happens first sends the alert. Either condition is enough on its own.
Without a custom rule, an alert fires when the price drops 9% or more. That default is what free-plan tracking uses on partner stores, and it can't be customized there — a target price or a different threshold needs Plus.
Alerts still come as batched email. Your rule decides whether an item is eligible; the email timing follows the normal batched 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?"
