Items? What kind of items? If you're talking XP boosters, crafting skillup boosters, etc, then yes you can buy those. If you're talking anything that can/will give you an advantage in game over someone who really hasn't bought it (omg levelling up cooking), then no. Those will not be charged for, because those types of advantages don't exist.
You can buy awesome armor skins though, to put ontop of your currently existing gear.
