Are you able to get RS Gold from websites?

As I can tell there are a lot of gamers and websites which sell Oldschool RS Gold online at affordable prices. However, as to me I'll first think about purchasing from a traditional site. I feel this is safer than finding buyers on the internet. I have a habit of buying from RSorder. Their price on the website isn't higher than that of the players themselves. The trick is to purchase more securely and their service is excellent.
