When selling age-limit products online to customers what sort of precautions should I take?

HALLAL_Kippah-Girl_JPAA asked:


I will be selling liquor online as a joint venture business that will be attempting to sell a range of fine products but there will be liquor in product line. This is going to be an online site and I am looking for suggestions on how to be user-friendly to adult shoppers but safeguard against an accidental sale to a minor.
