At first the website looks pretty suspicious, but since I was desperately searching for a service manual for my Suzuki GSX-R600, the cheapest price I could find was on this website, I decided to give it a shot. I made sure that the don't require card information and accept paypal instead. Actually paypal seems to be the only option they accept (which is good/safe). After completing the checkout flow, I was redirected back from paypal to aservicemanualpdf.com and I got message "Sorry, trouble retrieving payment receipt." and I thought that's it I was scammed. But then I went to my mail inbox and saw a new message with title "Purchase Receipt" and it actually had the link to the pdf file. It is a legit website, with nice prices compared to others. Hope this helps someone.
