A wishlist built well before a major sale event turns a chaotic shopping day into a much more targeted, efficient one - the difference between browsing reactively and executing a plan.
A wishlist built only in the days before a sale is rushed and incomplete - adding items as you notice them throughout the year produces a more thoughtful, complete list by the time a sale actually arrives.
Not every wishlist item deserves equal urgency - ranking the list means you know exactly what to grab first if a big sale creates limited stock or a narrow window before something sells out.
For the highest-priority items, a price tracking alert removes the need to manually check constantly during a sale - you'll be notified the moment the price actually drops to a worthwhile level.
