Tactics you can copy
- 01List on Amazon and switch to FBA: trade some per-unit margin for Prime shipping and more time to market.
- 02Start with one size and one age range (7-11) to keep SKUs minimal, then add colors.
- 03Offer a no-questions 100% satisfaction guarantee, even on opened or dirty items, to lower the purchase barrier for parents.
