There was someone selling them at the local farmer’s market ... I asked her, she said to dig a few and wait until they grow eyes, then replant.

I’ll try that.

Once you see some eyes sprouting from the potatoes, plant either whole, or good sizable chunks
If useing cut chunk, allow a day or two in the sun to form 'callous' (plant scab) to prevent fungal disease, or rot
.. then replant

Most store-bought potatoes have been sprayed with a hormone which inhibits easy sprouting.
and are designed to have potatoes stored for long periods of storage or longer with refridgeration.
