The $0 total means there's no upfront payment for your Shapermint Club+ Box. Instead, you'll have the opportunity to try the items at home before deciding what you'd like to keep.
 

Once your box is delivered, your 7-day trial period begins. During that time, you can decide which items to keep and which to return. You'll only be charged for the items you choose to keep, while eligible returned items won't be included in your final charge.

For details about your trial period and next steps, check your account or the information included with your Shapermint Club+ Box.
