These left the merchant feed within the last 60 days. A retired code sometimes still works at checkout, so it stays listed until the tracker drops it.
Costumes.com issues percentage discounts across the board, making the math straightforward for any cart size. We track 20 live offers, with savings reaching up to 50%, which is a strong setup for Party Supplies given the seasonal nature of the category.
All 20 offers are percentage based, no flat dollar codes and no free shipping codes in the current set. The codes span sitewide discounts and category specific promotions like Marvel costumes, giving shoppers choice between general savings and targeted deals. There are no first order restrictions in the feed, so codes work for repeat buyers as well.
Party Supplies sees predictable demand spikes around Halloween and the winter holidays, with deeper discounts arriving as those dates approach. Waiting until mid August through September typically yields the widest Halloween offers, while October sees codes narrow again as inventory tightens. If you need costumes for an event more than two months away, checking back in four to six weeks will likely show stronger codes than buying now.
All 20 offers on this page come from merchant and affiliate network feeds, never from user submissions, and the whole page is matched against those feeds once a day. An offer that leaves the feed is retired the same day and stays listed as retired for 60 days, because a retired code often still works. Nobody here writes a code by hand and nobody places a test order, so we never tell you an offer worked for us. A code that fails for you goes to the desk queue through the report button the same day.
Offers last matched against the feed: October 2, 2026. Page notes written by Bryan Ocampo.
Offers on this page are ordered by how much they take off, not by how recent they are. Read the line under each one: it shows when the offer entered the tracker and, where the retailer states it, when it ends.
Codes are not printed in the page. Selecting an offer reveals the code and opens the retailer in a new tab at the same time, so you can paste it straight into the cart.
Enter the code in the promo or discount field and confirm the total changes before completing the order. A code that applies but takes off less than expected usually means part of the cart is excluded.
If the offer does not apply, use the report button on this page. It goes to the desk queue the same day, and an offer that fails twice is retired.

The deepest discount on this page takes 50% off. 12 of the current offers read as sitewide, so they are not tied to one product line.
Not in the current set. None of the offers on this page are marked for first orders only, so what you see applies whether or not you have ordered before.
Check the terms under the offer first: most rejections come from a spend threshold, an excluded product line, or a first order restriction. If the code still fails, use the report button on this page. It goes to the desk queue the same day, and a code that fails twice is retired.
