Please note, we do not offer a military discount at this time.

Unfortunately, most manufacturer warranties do not apply to items purchased secondhand on our site. We do offer a 1 year protection plan if you would like to add that to your purchase. If you prefer a manufacturer warranty with your product, we suggest purchasing brand new from the manufacturer.

GoodBuy Gear's Protection Plan warrants select products to be free from any manufacturing defects for a period of one year from the date of purchase under normal use and in compliance with the operating instructions. More details.

With the largest baby & kid gear database in the industry, we have created an extensive, proprietary quality check process that each item must pass to be listed for resale.
