yes, I'be been making my own yeast bread for years. Buy the bulk pack at the wholesale club and leave it unopened on the shelf or in the freezer after opening: last for years
I've also experimented with "catching" live yeast by leaving the flour and water out. Results are variable, but it's definitely doable. If you get in that situation it would be ideal to save a bit of dough each time for a starter for the next batch.
