I agree that it is pleasant to save seeds but these days there is the
equivalent to PBR via hybrids. These are usually worth their extra cost but
cannot breed true if saved.
The work involved in producing such hybrid seeds is phenomenal especially
when compared with field harvested seeds that were the norm.

Surely, once you've grown your first batch of sunflowers, you need never
buy
the seeds again....

The commercial varieties of Sunflower are grown for their seed and oil
properties. Those you have purchased are most likely garden varieties
supposedly much more attractive than those grown in fields. They might
even
be dwarf or nearly double.
Those from the birdseed will be of the field variety.
