Hi @poocut - You have a very unusual hobby, of collecting cacti. The nice thing is they need very little attention - but the return so much joy.
It's a pity they are so expensive in your city. This too is unusual, many place you can find them cheaply, like here in my country.
if I can know where you come from?
very easy if buying cactus with cheap price.
if I have a chance to visit your country then I will buy a lot of cactus.
pray for me to visit there @rlt47
