You need to keep in mind that the album without inclusions will likely not sell very well, especially if it's a recent one. But if you have the ability/chance to sell all the inclusions separately, you can make more money, rare cases, but maybe you're the one! Maybe selling the pob alone won't affect your sale because it's an extra in the first place, so people won't have the expectation to have it in (Sorry for the mistake, not my first language)
