I know I've got a reputation here for not speaking my mind, for prevarication and obfuscation, but I gotta level with you here, only because you asked, scrap the whole idea IF you want to appeal to mainstream buyers.

Mom and Dad are most likely NOT going to be visiting your website or stopping at your table when they're out shopping for Little Timmy's new pet.

I'm sure you'll get all the 15 to 19 year old tatted, pierced, metalhead unemployed lookers that currently exist, maybe even some of the emo crowd, but how many of them have money to spend?

Target your market. WHO do you want to sell to?

And for those of you who are 15 to 19, have lots of tats and piercings, love metal music and are unemployed....get a job losers.
