I purchased this plant on clearance. What is it?

Melinda:

You are the proud owner of (Euphorbia milii). prefers bright light and well-draining

soil. It tolerates low humidity, making it well suited to growing indoors. Don’t be alarmed when the plant drops its leaves.

This is common and usually happens in winter. The root system is relatively small compared to the top growth, so don’t be anxious to transplant it to a larger container. Beware of the thorns that and pets, as well as the sticky white latex sap that can irritate the skin and eyes.
