While our return rate is low, we do get a few carriers returned during our 90 day trial period. We inspect all the returned carriers to make sure they are in good shape, wash them up and offer them at a discounted price. These Ergos still have the same 90 day money back trial with FREE shipping. We only have these pre-owned Ergos to offer, so they are available on a first come first served basis. Totals will be adjusted manually and will be confirmed after your order is placed. Extended 90-Warranty and FREE shipping.
