I wouldn't care at all if they cancelled my order. I was just trying to see if it would work. I'll be upset if they just go ahead and charge me full price though without warning.
I don't understand the account flagging either.. People probably just didn't read the $35 minimum. Not everyone is trying to defraud them or something. They should have just set the system up to only accept it for orders over $35 not let it go then "flag" everyone who didn't know.
Not that it matters to me personally at all..
