Yes! You're definitely able to do it. I just received mine from RSorder which was a great shopping Experience for me. I received my 300 million OSRS Gold in only three minutes. The process is simple too, just make your purchase and pay for it.
When I spoke with their customer service and was advised of the exact location and specific person to be looking for. When I arrived at the location, it was clear who I should speak to first. Within less than a minute the Buy RuneScape 2007 Gold had been transferred to my account, and I was able purchase higher quality armour and weapons to use as my primary.
