Query: rip off!

Prickly pear pads are available in many places for as low as 99 cents. They root easily from pad or pieces and can be obtained nearly everywhere. Twenty dollars is pretty much too much to pay for nearly ANY common opuntia. There are some rare opuntias, but this one is not and a tiny common cactus is not a good value for 49.99$That's my opinion. Do research and don't buy this!
