PetSmart...puppy classes

[BunsenBerners]

What's the story on these.  One of my puppy people wants to take classes here.  My 
first reaction is UGH.  What do you all think?  Does anyone know their training 
methods?  Are they positive or negative trainers?  Does it vary by area or is it 
consistant?  I am located in CT.  Thanks.
