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 and Sell Used Baby and Kids’ Clothes 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.
