IMPORTANT: I ask the sellers to simply rinse and store the eggs in the fridge until I arrive. One time a seller scrubbed the eggs clean with a Brillo pad! This could damage the cuticle of the egg and scratch the surface, spoiling it. So a gentle note to the seller is all that is needed.
DISCLAIMER: AS ALWAYS BE CAREFUL/CAUTIOUS WHEN BUYING OR TRADING ITEMS FROM CRAIGSLIST!
