The 13 Best Places To Buy & Sell Second Hand Kids Stuff

Where to shop for toys, kids clothes, gear, and more.

Knowing the best places to buy and sell used children’s clothes is one of the top parenting hacks for surviving a major growth spurt with your wallet (mostly) unscathed. This knowledge also comes in handy when you want to save a few bucks on back-to-school shopping, gifts for birthdays, or even a toy box refresh. Shopping for kids clothes and toys second hand can be a total life-saver, but you have to know where to look.

I’ve been a mom for more than a decade and the second hand kids clothing market has definitely changed for the better in recent years. Long gone are the days when you had to sift through racks of old baseball tournament tees to find one measly toddler-sized Gymboree shirt with stretched out arm holes. Not that there’s no value to be found in the aisles of your local children’s thrift store — they sometimes house absolute gems — but now, there’s an easier way to find exactly the kind of second hand kids stuff you you’re after.

There are some amazing websites fully dedicated to buying and selling used children’s clothes and second hand toys, as well as some popular resale sites that have a vast kid’s selection alongside their other offerings. Whether you want to buy top brands for less, sell outgrown items, or just find a new winter coat that doesn’t break the bank, these are the best places to find second hand kids stuff.


Kidsy is an online marketplace with thousands of second hand kids clothes, toys, books, and gear listed by real parents. Shop for the kids items you need by condition (new with tags, new without tags, good, fair, or functional with defects), by brand, item type, and delivery method. Message sellers directly with questions, make an offer, or buy it immediately for the price listed. If you list your own second hand kids clothing or toys for sale, you get to set the price, and are responsible for packaging and shipping your items. Kids takes a small 5% commission on every item sold.

What they offer: Children’s clothing, pajamas, outerwear, shoes, and accessories, plus kids toys and gear.

When selling clothing, the site does not accept discount brands such as Old Navy or Target’s Cat & Jack brand, but they will accept Carter’s and Baby Gap items if they’re new with tags. All items are sold on consignment, and some conditions and fees may apply to items, depending on condition. Once your items sell, you can choose to receive a cash payout via PayPal or Venmo or an electronic store credit.
