This role supports Spirit Halloween's unique operating model, where stores open for a concentrated selling season and require precise pre-season planning, agile in-season decision-making, and disciplined post-season analysis. Partnering closely with Merchandising, Allocation, Store Operations, Supply Chain, Logistics, IT, and Finance, the Merchandise Planner ensures inventory is positioned in the right stores, at the right time, and at the appropriate depth to maximize sales, margin, sell-through, and inventory productivity.
