Just a suggestion, for whatever it's worth: consider changing the URL to the product page to something more intuitive.
Right now, the URL is: http://paizo.com/products/btpy84k4
Consider changing it to (or redirecting it from) something like: http://paizo.com/pfsguide
When I tell a player that they need the guide, and to go download it from paizo.com, they have to poke around on the site to find it. It's not hard to find, but there are some folks out there that just don't/can't/won't find something by poking around on a website.
