But if they are willing to give a discount, go for it. They probably just want to hear about new test questions.
Well...no one can guarantee that the sun will come up tomorrow either; but I'll bet a dollar on it

Of course no one can guarantee anything - but if you will check out the first sentence under the header of the page and the first bullet then you will see what I was passing on.
It is a good enough gaurantee that IF YOU SEE a question on the test that wasn't on the prep bank then then will give you a discount/refund
