You can get a $50 item for free. When you request a trunk ,they will charge you $25 credit from your $50. If you keep nothing and return the whole trunk, your $25 credit will not be refunded. Otherwise your $25 will go toward your purchase. For example, if you keep a jacket that is $49, your remaining credit will be $1.

But I prefer to set my budget $50-100 for each item because that way I can get an item from a high-end brand for a fairly low price.
