Although I saw the offer on their site, but cannt say much about the discount, but product is really good and they are giving repeat customer discount, collection discount and now discount on some test kit. Have to look for it. I had recently visited uCertify they are offering 40% and 50% discount schemes on their Oracle kits. I downloaded its questions for exam 1Z0-147 questions are on right quality. Collection is one of good offer where we can make our own collection. Several product in market like measureup, test king, passguaranteed, transcender etc. Some good books should you have to prefer to understand the whole concept.
Maybe it's an advert for one of those programs that re-writes content to try and make it look unique?
