Babies and kids grow out of their clothes in months, even weeks; sometimes outfits are never even worn. Ditto re kids’ gear such as strollers or car seats: you’re done with them well before their useful life has passed. Buying –and selling – kids’ stuff that is just used makes financial sense.

The opportunities to snag great deals on used kids’ items are no longer limited to yard sales or brick-and-mortar consignment shops. Now you can buy, sell, or swap them online, from sites that specifically cater to parents and kids.

Buy, Sell, and Swap Used Baby and Kids’ Clothing & Gear

ThredUP.com

thredUP.comUsers of this site can buy, sell, and swap high-quality clothes and items for kids and for women through a program much like an online thrift or consignment shop. Sellers ship their like-new, name brand items to thredUP using prepaid shipping labels, and choose 1 of 2 methods to sell their items.  With the “upfront sales” method, they sell their goods outright to thredUP for 10- 40% of what thredUP estimates is a fair resale price. (The site includes a “calculator” to estimate what you might be paid.) With “consignment” sales, sellers consign the items to thredUp and get a percentage (50- 80%) of the actual price the item is sold for, if it sells. thredUp promises that all items are  carefully inspected before being listed for sale. Buyers pay reasonable shipping fees; free shipping for orders over $50. Examples of children’s items recently for sale: Rocawear zip hoody, $17.99; special occasion dress from The Children’s Place, $13.99.

Swap.com

Swap.com is another online consignment shop where users buy, sell, and swap kids clothes, maternity clothes, books, toys, games, and movies. With prepaid labels, sellers send their items to Swap.com’s warehouse, which categorizes, photographs, and stores the items. The site then posts the items online at a price set by the seller. When a buyer makes a purchase, Swap.com ships the item to the buyer. The fee structure for this full-service process is complicated, but the basics are that the seller pays Swap.com an $8.90 processing fee in addition to a commission of $1 plus 20% of the sales price. Examples of items recently for sale: Fisher-Price baby monitor, $15; Motherhood Maternity dress, $9; The Children’s Place girl’s hoodie, $5.

SwapBabyGoods.com

SwapBabyGoods.com. This is a Craigslist-style, free online marketplace for buyers, sellers, and swappers of baby clothing, toys, gear, and other goods. For no charge, sellers can list their items for sale or swap on the site. Buyer/swappers click on the listing for detailed information, such as whether the item is from a smoke-free home, what type of payment is acceptable (usually PayPal),  and whether the item is available for pick-up only or may be shipped to non-local buyers. Buyers and sellers/swappers then arrange and implement their own transactions. SwapBabyGoods.com asks buyers/swappers to provide feedback about their transactions in order to rate sellers/swappers. The site also offers a “wanted” section where members can list items they are seeking to buy or swap. Examples of items recently for sale: Baby Bjorn baby carrier, $30; Hoala Baby Boutique dress, $5; train table and Chuggington trains, $65.

Buy and Sell Used Baby and Kids’ Clothes

 Loteda.com

Loteda.com. This recently launched site connects buyers and sellers –- taking a 10% commission from the seller — of lots of clothing (boxes of 4-50 items), rather than individual pieces. Sellers sort their clothes by size, gender, and season to create a box lot. They then take their own photos of the items in the lot and upload the photos to Loteda. Sellers set their own price for the lot, which must include shipping costs. Buyers purchase the lots through the Loteda website. Loteda then provides the sales information to the sellers, who ship their lots of clothing directly to the buyers. If a buyer does not seek a refund within 3 days, Loteda will send a check to the seller for 90% of the sales price. Examples of lots recently listed for sale: 12-piece baby girl clothing, including Carter and Child of Mine brands, for $24; 4-piece lot of toddler boys sweaters by Gymboree, Bowen& Wright, and The Children’s Place, $12.  Note: Since Loteda is so new, its inventory currently is low; presumably that will improve as more people find the site.
