I'm plan to sit for the 70-270 within the next couple of weeks and am about to purchase the exam insurance just as an extra precaution.
Microsoft only list a handful of testing centers in my area from which to purchase the insurance, but this site offers it for a discount:

Has anyone ever dealt with GetCertify4Less.com before? I'm just wondering how legit they are before I proceed.
