Kids are brutally honest about costumes — if it's itchy, cheap-looking, or not the character they wanted, you'll hear about it all night. Every costume below is on sale right now at a Canadian retailer, in stock in kids' sizes, and verified — we load the product page and confirm the price before it makes this list.
Popular kids' sizes sell out first as October 31 approaches. We check these daily and pull anything that sells out, so don't wait if you see the right size.

We load each retailer's product page and confirm the sale price, the original price, and that it's in stock. Every costume shows the exact time it was last verified. A blocked or failed check never counts — if we can't verify it, it doesn't make the list.
That depends on the retailer and your postal code — check the delivery estimate on the product page before you buy. Ordering early in October is the safe move.
It comes off the page automatically, and a verified backup takes its place.
