Age Verification on Bigcomerce Website

I seriously don't get why the average bid is so high ($142 as I type this). If I understand correctly, all you're asking for is to add a field where you ask the user for their date of birth, then only allow the ones over 18 to enter, right? If that's the case, don't let them take advantage of you seriously I don't know why people are bidding so high on this. What you're asking for is in no way worth over $100.
