I can/will never get any credits to buy some stupid things to look more sexier in a game or somehow in another thing. The game is a game in all it ways and you should be good in it by your own self and taking it a little serious.
Anyway if my dad accepts to add 5$ to the credit card I'd thank him a lot because like that i'll be adding 400 or 800 (I forgot how much) so I can buy a skin in LoL :3 RoYaL SHaCo !
