Fulfilment by Amazon (FBA) is a service we offer sellers that lets them store their products in Amazon’s fulfillment centers, and we directly pack, ship, and provide customer service for these products. Something we hope you’ll especially enjoy: FBA items qualify for FREE Shipping . We also offer our FBA customers the option to use our 3pl Fulfilment service to send their inventory to different Amazon fulfillment centers. And now, if you want your product sent to an Amazon FBA fulfillment center but you don’t want it stored there, you can use CSG3PL to pick, pack, ship and provide customer service on your own. This means that a seller can now fulfill an order from its warehouse or store using CSG3PL Fulfillment service. Then, if the order is going to be fulfilled by Amazon – for example, because it was a 1-Click order – the seller can use its Seller Central account to send the item directly to an Amazon FBA fulfillment center.
