can i apply mutiple item codes on the same account?

[tilldagmar]

as the title suggests, just wondering if it is legal or even possible to do so, does it violate any of Sega's rules? coz im gonna sell the items and make some extra scratch, for the item enchantment system is just preposterous, it drains every penny on me.......
ps: its the vita physical copy item code, i have owned one since its released and now im considering getting another one to make some money, ac scratch is kinda full of shit.

As long as you own the code. No two codes are the same though, and if you have to enter it on the PSN it might not work due to duplication prevention stuff.
