The Fulfillment Lab (GFS)

Don't waste your time with Fulfillment Lab. In my experience working with them, at least 10% of orders on a monthly basis are incorrect, shipped late, or do not contain all items in an order. Working with their customer service teams is like pulling teeth and when they do respond they're usually very rude. They also botched a product launch of ours by failing to inventory items sent them for over a month. Completely mismanaged on the CS side and led by sales people who will say anything to close a contract, even if they actually can't promise what they communicated. Go with SaltBox or self-fulfill.
