Advice: Protecting myself in regards to premades

[goatparty.livejournal.com]

I'm trying to break into the fursuit commission business, and so far I'm just selling premise bases and tails.

Seeing some recent posts here about underage people buying things and having the parent/guardian file chargeback has me worried, though.

Is it safer for me as a seller to list my items on sites like Etsy or The Dealer's Den rather than letting people buy directly from me via Paypal?
