When we talk about seed-saving with potatoes we are usually talking about tubers, not seed. Saving your own tubers and re-planting them is frowned upon for the same reason as using supermarket tubers; it can lead to virus diseases. If you want to save your own seed potatoes, just store them very carefully and don't eat them.
You may want to experiment with actual potato seed as well. Many varieties don't usually produce seed, but some do. It can be gathered from any ripe fruits your plants produce. These take about two months to ripen and may be green or purple. Squeeze out the seeds into a bowl and wash them. The good seeds sink and bad ones float.
