Nanacast doesn’t support the traditional shopping cart concept where customers add multiple items to a cart, click the checkout button and pay for them all at once. Nanacast was created for internet marketers that are selling digital products, services or memberships. Once the person decides to purchase that product, service or membership, Nanacast can then show them one-time offers, upsells or downsells sequentially. Finally, Nanacast provides the digital product delivery by letting your customers download the digital products via secure, expiring Amazon S3 links. So, if you’re selling physical T-shirts or separate PLR products like Tradebit, Nanacast is not a good fit. If you’re selling a video course on starting a T-Shirt business, Nanacast is perfect for you.
