I am looking to buy halloween contacts without a prescription...?

Okay so heres the story:
I'm 15 and I wore glasses all my life until 7th grade when my mom allowed me to get contacts.I worn them for like 3 weeks but I (as a 12 yr old)got lazy and stopped useing them and pretended like I was wearing them.When my mom found out, I told her I didnt really need any kind of prescription eye care because at that point my eyes were able to see fine without.Well now it's 3 years later and I want to buy halloween contacts.But most sites require a prescriptio which dosnt exist since it has been over a year and the eye people cant give me that prescription (I need for eye diameter ect.). Getting another prescription is $100+.That is ALOT.

Is there any links that you may know of that I can buy NON-PRESCRIPTION halloween contact lenses that dosent charge me a boat load?(By non prescribtion I mean they dont need optomitrist information ei.phone #'s)

PLEASE help!

www.vampfangs.com is one place that I know of. There are always add's in the back of gothic/metal magazines for costume gear; you might even get lucky at hot topic, but its doubtfull they would carry contacts.
