Customer Service


Returns:
All returns must be made within 30 days of purchase. A Return Merchandise Authorization number is required for all returns. Please email us through the eBay system to obtain a RMA number. Buyer is responsible for all return shipping costs unless item was shipped in error by seller or is defective. Any item returned to us in non-brand new condition and/or not in original packaging (ready to sell) is subject to a restocking fee. Any return is subject to refusal if the item is damaged beyond usable condition. We do not do "exchanges" - you can return the incorrect item (you must obtain a RMA number to do so) and will be refunded according to our return policy for it. You can then purchase the correct item at any time.

Emails: Please contact us using the eBay message system only, this is a requirement of eBay and ensures we will see your message.  Every effort is made to answer all questions within (1) business day – we are closed evenings, holidays and on weekends.  Any question sent during those times will be answered during the next business day.

Feedback: We value our feedback rating tremendously as it helps determine customer satisfaction. Our feedback is left automatically after we receive it because we don't consider the transaction complete until our buyers have received their order and are satisfied. If you feel the need to leave anything other than positive feedback, please contact us first.  We will try to resolve any issues, but we can’t rectify a problem if we are not aware of it.

Warranty:  Some items are covered by a warranty. Please contact us with any questions about a warranty on a particular item.  Most are manufacturer's warranties and must be handled directly through the manufacturer.
