That's a good description, Jerry. Many growers are not fans of this method, tissue culture due to the plant quality issues, weaker cells thus weakened garden plants with the same names as their fully root grown counterparts but not growing as well...possibly giving a named award winning plant a bad rap.
Not all "advances" are positive ones.
I too like a deal. But somehow deals like tc never work out that well for me. That and with limited space, I find a NOID white scentless white peony that takes three years to bloom, called 'Sarah Bernhardt' not very funny. Ugh. (I digress...)
