This lady is selling this plant as a rhipsalis agudoensis. I love the plant and want to purchase it but I am almost positive it's not Rhipsalis. Could it be some kind of Opuntia prickly pear dwarf? I really want to know the correct name for it. Thank you

I think you are right, it certainly looks more like an Opuntia to me....

...this one is Opuntia basilaris, and I found a few others that might fit the bill...

This appears most similar to Brasilopuntia brasiliensis, a monogeneric cactus (Cactaceae) native to tropical South America. It would be good to see the plant in flower for a more definite identification.
