How can I effectively save seeds from store-bought vegetables for future planting?

To effectively save seeds from store-bought vegetables for future planting, first choose a healthy, ripe vegetable from which to extract the seeds. Remove the seeds from the vegetable, clean off any pulp or debris, and allow them to dry completely. Store the seeds in a cool, dry place in a labeled, airtight container. Make sure to keep the seeds away from moisture and sunlight to maintain their viability for future planting.
