Ruby Lane is a website / marketplace for antiques, collectibles, art, and jewelry. Sellers set up shop and sell their merchandise in a similar way to eBay and Etsy.
When sellers ship their merchandise, Ruby Lane requires that all shipments be insured unless declined by the buyer using the Decline Insurance option during the Checkout process (http://kb.rubylane.com/question.php?ID=339).
Shipsurance offers full, all risk shipping insurance coverage to Ruby Lane sellers at great discounts to the shipping carriers. Click here for more details or visit http://www.shipsurance.com/rubylane
