We highly suggest you set up an account so you can track your order, shipments and make any returns easily.
A core charge is a deposit paid for your used part. When you return the used part and it is a good core we return your deposit to you.
UPS will be used for most all of our shipping. However for parts over 150lbs we use various freight carriers.
We use Secure Socket Layers (SSL) to encrypt all transactions that require personal information.
