Not only snow blower. One time we had bought something small, but realized we bought the wrong item, so we went to return it (it's not even opened yet), but they gave us a very very horrible hard time (not to mention their bad attitude). Finally we returned it, but only because we were screaming and sure it caught some customers attention.
My conclusion is if you want to buy anything from CT, make sure you won't return it, or you are 100% sure of the quality (which means you have to be 100% sure of the item would work perfectly after it walked out of the door), otherwise, strongly recommend you to go to another store, even if you have to pay more, it just doesn't worth your time and energy to argue and scream inside the store.
