Customer Service

We ship nationwide at the same cost as a local delivery! excluded

Most orders will be shipped the same day by one of our carriers. Because of our huge volume, we have negotiated special rates with certain shipping companies to bring you the lowest possible freight costs. Once you have placed an order with us, you will receive a confirmation email containing the shipping information, shipper contact number, estimated delivery time and a tracking number.

All products are inspected before delivery. However, damage may occur during shipping. We request that customers inspect all products at time of delivery.

AVA does not assume any responsibility for any damage or missing parts claims after inspection and signing by the purchaser at the time of delivery. Please make damage claims direct to the carrier for orders shipped via common carrier.
