I need some one to audit websites

We have a client who has links to go and buy their products e.g Films on iTunes, Google or Amazon. We want to check if they exist and actually work. I.e they link to a product page where you can buy that title. Please see attached files with the instructions on how to do this audit and let me know if you have any questions.

I'd suggest you send us a sample to check and then we can confirm if you are on the right track. On the attached excel there's an example for the title "300", using that one as a reference audit the two titles below "Wonder Woman" and "2001: A Space Odyssey".
