Returns Policy

Most new, unopened items can be returned for a complete refund, and if the return is due to our mistake (for example, you received an incorrect or defective item), we will cover the cost of return shipping.

Typically, you can expect to get your refund within four weeks after handing over your package to the return shipper. However, in many instances, you may receive your refund even faster. This four-week timeframe encompasses several stages: the transit time for us to receive your return from the shipper (which typically takes 5 to 10 business days), the time needed to process your return once we have it (usually 3 to 5 business days), and the time your bank takes to process our refund request (typically 5 to 10 business days).
