Yes, Sylvester, you can sell digital products on Amazon, whether they are eBooks or software. If you have written that book or developed that software, then you can go with the private label; there is no issue. But if you want to sell the eBook of any other seller who is selling the same product on Amazon, then without his permission, you can’t sell his books into the Amazon marketplace as a private label, and the same is true for the software.
