KMJ PERFORMANCE - TECH AND RETURNS - Please use the eBay messaging system for any returns or technical assistance MONDAY-FRIDAY: 8:00AM-5:00PM SATURDAYS: 8:00AM-4:30PM (CST)Click on store image to view our current listings of High Performance Products! Payment: Please make payment within 7 days of purchase. Paypal and Visa/MC/Discover credit card payments are accepted. Please use the eBay message system if you have any questions or need assistance. PAYPAL PAYMENTS - The majority of Paypal payments can be processed within 2-3 hours after received during our normal weekday business times. To prevent any delays with your order you should watch for the following common issues: Be sure your shipping address has a physical address that Fedex/UPS can deliver to. Addresses that only have a PO Box can cause long delays and almost always result with having to credit/cancel the order in the end. You should be able to add one onto your payment when going through the payment process. Be sure the shipping address is correct when making payment. Shipments will go to the address that comes through on the payment. Within a short time it may be already shipped and on the way. Some of our listings may request a "note to seller" to let us know if you have a certain preference or need a specific thing such things as sizes, colors, etc. Putting a note on your Paypal payment is the best way to insure it should not be missed. In order to comply with Paypal's buyer/seller protection policy, any (single) payment having a total of $750 or more must be sent with signature confirmation on delivery. This applies to all packages that may be associated with the payment. If the order requires multiple packages someone will need to sign for each one. If you find there is any problem with your payment or order we recommend calling us during normal business hours if at all possible. If you miss us during regular hours you can leave a voice mail message on our phone system. While we do our best to keep up with eBay messages, during times of heavy volume an order can get processed and shipped before we're able to get through them all to stop or change an order. Shipping: Unless a listing is set up that allows calculated shipping for other locations, the shipping amount given for an item will be ground shipping to the lower 48 states only. We do not offer any next day, air freight, or other expedited services on eBay orders. We try and combine EBay auctions when possible. Normally it will be the highest shipping amount plus half the shipping amount on other items, sometimes better on orders of small items. Some items are not combined due to size or weight such as crankshafts, torque converters, radiators, cylinder heads, etc. On multiple item purchases the shipping amount is not figured automatically during checkout so please request a new invoice or wait for us to send a combined invoice so we can adjust the total. We may have auctions that state free shipping when purchased with certain items. If purchasing items with free shipping, please request a new invoice before paying. The shipping amount is not figured automatically during checkout. We are unable to refund your Paypal once payment has been sent. If you have any doubt what your shipping will be please feel free to message us during business hours. Powered by SixBit's eCommerce Solution
