Shoppers planning ahead for Halloween have a reason to mark their calendars early this year. Dillon’s Halloween Depot has announced a site-wide costume sale running from September 1 through September 15, offering 40% off every costume in its catalog.

The discount applies across the store’s full costume lineup, which spans multiple subcategories covering a wide range of styles and sizes. Unlike typical last-minute October discounting, this early-September window is aimed at shoppers who want to lock in their costume choice — and their size — well before Halloween-week inventory starts to thin out.

The sale is scheduled to end automatically on September 15, with pricing reverting to standard rates afterward. Decorations, party supplies, and candy are not included in the promotion, which is limited to the costume department specifically.

The sale can be found at dillonshalloweendepot.com starting September 1.
