To qualify for a return or exchange, the following conditions must be met:

  • The item must be in new, unused, and uninstalled condition.

  • All original packaging, tags, hardware, and accessories must be included and intact.

  • Items showing wear, installation marks, damage, or improper use cannot be accepted.

  • An order number is required.

Once your return is received at our warehouse, a refund will be issued within 5 days after inspection.

Refunds

Refunds are issued to the original form of payment once the returned item has been received and approved. If we are unable to refund to the original payment method, the refund will be issued as store credit.

Depending on your bank or credit card provider, it may take an additional 2–3 business days for the refund to appear in your account. 

Exchanges

To make an exchange, simply complete the return process and then place a new order for the item you want instead. This ensures the replacement item is reserved and ships quickly.

How to Start a Return
