Why upload early?
- New listings take 1–2 weeks to index fully in Amazon search.
- Early sales and reviews push your design up before the search-volume peak.
- Big events (Christmas, Halloween, 4th of July) need the longest lead — about 75 days.
- Shoppers buy gift shirts 2–4 weeks before the actual date, not on the day.
