Pass It On

Outgrown children’s clothing deserves another adventure (or two). Buy well. Resell. Pass it on.

Sell what they outgrew. Take 110% of the sale price in Firebird credit, or 80% in cash.

"73% of apparel is sent to landfill or incinerated, 95% of which could be reused or recycled." - Ellen MacArthur Foundation.

Firebird Kids is on a mission to help parents dress their children well while reducing the pile-up of cheap, outgrown clothing cluttering their closets.

Our signature ‘Pass It On’ resale platform allows you to buy and sell outgrown Firebird Kids clothing at reduced prices for credit towards your next purchase, making it both easy and rewarding to invest in high-quality, sustainable clothing for your kids.

Made with quality and timeless design, our clothes belong with another child, not in a landfill. Buy better, use better, resell, repeat.

How It Works

  1. List your outgrown piece: Create a free Pass It On account on Treet (it is separate from your Firebird Kids login; use the email you ordered with and your past orders appear, ready to list). Upload photos, describe any wear, and set a resale price. Every listing is reviewed within 24 hours.
  2. Ship it: When it sells, you get a prepaid shipping label by email. The buyer covers shipping. Once the post office scans the package, you are paid in full even if it is lost in transit.
  3. Choose your payout: 110% of the sale price as Firebird Kids credit, or 80% of the sale price as cash by direct deposit within 7 business days of the buyer confirming the piece. A $40 sale is $44 in credit toward the next size, or $32 in cash.
  4. Shop pre-loved pieces: Browse verified second-hand Firebird Kids styles at thoughtful prices.

The Terms

  • Credit: 110% of the sale price, no fee. It arrives by email as a code for firebirdkids.com, does not expire, and is used in one order.
  • Cash: 80% of the sale price (Treet keeps a 20% fee), paid by direct deposit within 7 business days of delivery and buyer confirmation.
  • Sellers must be in the United States. Buyers pay shipping.
  • Only Firebird Kids pieces in good condition. Describe any wear honestly; every listing is checked before it goes live.
