Special pre-order cancellation policy

Orders containing both preorder and in-stock items may have the preorder items canceled at the customer’s request. Preorder cancellations and/or modifications must be requested no later than seven (7) business days prior to their release date. In cases when there are GPUs/Video graphic cards, Mining machines (GPU miners, ASIC miners) in the preorder, it cannot be cancelled after the confirmation of delivery from the manufacturer until the preordered items have been received by our warehouse. Cancelling preorder items may result in a 15% cancellation fee. Refunds, minus the cancellation fee, are issued to the original payment method.

In some circumstances, you can charge a restocking fee when a buyer returns an item. These circumstances include when an item is returned outside of BMMC return policy or in use, damaged/defective, or materially different condition. Items returned in original condition and within policy cannot be charged with a restocking fee. You are not required to accept returns beyond the return window. However, if you do, you can also charge a restocking fee.

A restocking fee is a percentage of the item’s price; depending on the type of item and its condition upon return (item price does not include shipping costs). Only returned items are eligible for a restocking fee. The refund workflow will help you calculate the restocking fee for eligible items, and deduct it from the refund you issue to your customer based on the guidelines outlined in the table below.
