I found this image on Google.
My Razer Death Adder mouse broke today, so I returned it to Razer and they are sending me another. I had to show them a receipt just like this one in the email I sent. (From Amazon.com and everything!)
I was wondering if I could abuse this with Razer (Or other companies.) by Photoshopping the text to say I bought the product. Since Razer doesn't have access to Amazon.com databases, they can't prove anything, right?
