I was going to book my 70-272 exam today but the Pearson VUE site says that \nthe 15% discount voucher code that I have is not valid. (The voucher says \nit is good worldwide until June 30, 2006 & I scratched it only today). I \nseem to remember that I had a similar problem in 2003 when I booked an exam. \nI think I ended up calling the call centre to get the discount. Has anyone \nelse ever encountered a problem using the exam discount voucher code from an \nMSPress book before ?\n\nThe second chance promo code worked without a hitch, but I'm such a deal \nhound that I need to get the 15% discount as well.\n\nI couldn't get through to the call centre today, so I'll give it a shot \ntomorrow. Since this is the second time I come across a problem I was \nwondering if there was a general problem worth raising.
