where can i find empty percription bottles??

hey everyone i am turning 17 next month so, naturally i have already started planning for it, i am having a doctors themed party, to be more specific a [H]ouse md themed party, and i think it would be super fun if i could find bulk precription looking containers like house's vicoden to pour everyone shots in...so i need to know where a good place to look for them may be.. also if u have any other ideas please tell me!
