within 21 days from the time your order is received. If you return your core

OPTION 2: You can defer the core charge. If you defer, you will not be charged for the core at the time of purchase. You will have 21 days from the time your order is received to send the core back. If the core is not received within the 21 days, your credit card will be charged for the core amount on your order.
