2026 Halloween Costume Shopping Calendar: follow this chart to buy without rushing and without wasting money.
Every year in the last week of October, the same scene plays out at every Spirit Halloween store: parents rush in with their kids, and the shelves are left with only torn packaging and a few lousy "zombie prisoner" costumes, priced 40% higher than three weeks ago. Long lines form at the checkout, and every face says the same thing: I will definitely buy earlier next year.
And then next year it's the same.
The situation in 2026 is more worth planning ahead for than in previous years, for three reasons. First, total Halloween spending is expected to reach $13.5 billion, with costumes being the largest single category at $4.4 billion. Second, nearly 70% of Target's Halloween line this year is new, and 60% is exclusive, and it started selling out as soon as it hit shelves on August 12. Third, the "Summerween" trend has 70% of consumers starting to buy Halloween stuff before September, so by the time you remember in October, the popular items are long gone.
So this calendar is here to help you get ahead of the game. No rush, no wasted money.
July: Recon Month — Look but don't buy, but look in the right places
The most important thing in July is just one: figure out what costume you're going to wear this year.
Search data gives a very clear signal: searches for Halloween costume ideas have risen 220% in the past three months. Everyone is doing their homework early, and you don't need to be an exception.
Things to do in July:
Look together with your kids. Let them browse Target and Spirit Halloween's online catalogs, and check this year's trends on Pinterest and TikTok. Popular directions for 2026 include Rumi from KPop Demon Hunters, classic vampires and witches, and the cloak-and-mask look from The Traitors finale. Let the kids choose for themselves, which is a hundred times better than arguing with you in front of the shelves in October.
Record prices. Take screenshots of the styles you like and note the original price. This is your only reference for later judging whether "buying now is a good deal".
Don't place an order. July prices are basically full price for the year. What you're buying is not "locking in early", it's "spending more early".
August: Early Bird Month — Target's exclusives and Summerween discounts
August is the real "start of the shopping season" for 2026.
On August 1, the Spirit Halloween flagship store opens. The flagship store in Egg Harbor Township, New Jersey opened its doors at 7 a.m. on August 1, and other stores began opening in vacant retail spaces starting in early August. This is a "you can skip it" signal. What Spirit Halloween opens in August is a "display season", prices aren't optimal yet, but you can go to physical stores to feel the materials, try on sizes, and check the field of view. Especially for masks and wigs, seeing them online is completely different from wearing them on your head.
On August 12, Target's Halloween collection launches; this is the one 2026 date worth marking; Target's costume line this year is nearly 70% new and 60% Target exclusives, covering toddler to adult sizes; the headliners are the Rumi costume from KPop Demon Hunters and the expanded Pokémon line, which grew from 10 items last year to 26, including Pikachu and Jigglypuff; and the prices are very reasonable: half of the costumes and accessories are priced under $25
August 24 to September 20, Groupon's Summerween sale; a great chance to buy costumes and party rentals early, with discounts covering Halloween-themed events and costumes
The core strategy for August: if Target has the exclusive your kids want, act now; data from before last Halloween showed Target exclusives started selling out of sizes by mid-September, and by October only catch-all options like zombie and prisoner were left
September: golden month —— the most choices and prices start to soften
September is the best window all year to buy Halloween costumes, bar none
The reason is simple: 60% of Halloween costume sales happen between the last week of September and October 31, and retailers' promo cycles kick off in full by mid-September
Mid-September: the first wave of discounts appears; drugstores and supermarkets start pushing buy one get one and second item half off; Spirit Halloween sees a 30% to 40% markup peak between September 16 and 30, meaning the first half of September is Spirit Halloween's relatively lowest-price window of the year
Kids costumes: must be handled in the first half of September; professional retail analysis is very clear: buy kids costumes before early October; because kids sizes have the deepest stock but sell out fastest, medium and large sizes for popular characters start disappearing by the end of September
Adult costumes: you can wait until mid-October; adult sizes sell through more slowly than kids sizes, and the discount window for adult costumes comes later; analysis suggests buying adult costumes between October 16 and 25; but only if what you want is not this year's hottest IP, if it's KPop Demon Hunters or Wednesday related, you need to act in September
October: sprint month —— buy candy first, watch for costume discounts
October moves at a completely different pace
Candy: buy before October 20. Candy prices shot up badly in 2026 and cocoa prices have stayed high. The bulk candy at Costco and Sam's Club before October 20 is the best deal of the year; once October 25 passes, supermarket candy shelves are basically picked clean and everything left is a brand you have never heard of. Gummy candy and lollipops have barely moved in price while chocolate has climbed the most, so letting chocolate make up a third of the candy bowl is plenty
Costume: it depends on the retailer, and the split is huge
Target starts its first price cuts on October 3, usually knocking 30% off first, but note that Target begins markdowns a week before Halloween, and last year Home Depot had Halloween decoration at 50% off on October 27, so if you see decoration or accessories you like already discounted in late October, don't hesitate, that may be the bottom price
Spirit Halloween peaks in price between October 16 and 30, 30% to 40% above July baseline prices, so unless you really have no choice, don't buy full-price costume at Spirit Halloween in late October
Amazon has a Tuesday flash sale rhythm, so you can camp out on Tuesdays in October for specific accessories and makeup
November 1: clearance day — not wait until next year, but buy at the bottom now
The day after Halloween ends is the cheapest day of the year
Target's clearance ladder is very clear: November 1 (Sunday), decoration and costume go straight to 50% off, candy 30% off; November 3 or 4, most stores reach 70%; November 5, 90% off appears
But there's a key detail: the 90% off window is very short; it's not lasting several days, it's the final markdown, gone once sold out; in 2025 Target's Christmas clearance, 90% off started January 7, shelves were empty by January 11, four days, not forty-eight hours
Candy never reaches 90% off; Target's chocolate candy maxes out at 70% off, never 90%, so if you want to stock up on next year's candy, the window is between November 1 and 3
But there's a harsh fact: Halloween costume resale value in November is nearly zero, and a licensed character costume worth $25 in October may be worth only $3 to $5 by mid-November, and it might not even sell, so if you plan to buy for next year, going to physical stores to buy at the bottom on November 1 is more worthwhile than buying on resale platforms
In one sentence
Buy kids costume in September, adult costume in October, candy before October 20, and wait for clearance on November 1
Halloween shopping in 2026 is not a question of when it's cheapest, but a question of when there's still a choice; popular and exclusive items disappear in September, and if you wait until late October to go out, the shelves you face are a different world from what you saw in July
