In A Nutshell: Because, c'mon, you know that any money made while consigning goes to more shopping anyways, this site provides the awesomest service: clothes for gift cards! Instead of selling your used items, it appraises everything and offers a voucher to Shopbop, Saks Fifth Avenue or Bloomingdales in exchange.
Effort Required: Only the energy it takes to clean our your closet. Material Wrld will go through any items you submit (heads up: they don't accept fast fashion or mass market brands, such as Zara, Gap and Anthropologie), and email you a gift card quote. Should you accept it, the voucher will arrive in the mail within one to two business days.
Your Cut: A Shopbop, Saks Fifth Avenue or Bloomingdales gift card based on the value your unwanted clothing.
Fun Feature: Before sending anything in, you can check its value on the site's handy "quote look up" widget. It gives a decent idea of how much they'll offer.
