Alan,
Bob Smoley's Gardenworld has Haqorthia cooperi for $3. It does not have the var. obtusa after it. May not be the same as what you are looking for.
Arid Lands Greenhouses has Haworthia cooperi var. cooperi 4-inch pots for $6. Looks simular.
Check out the others. Also Bob doesn't show pictures of all there stuff.
