Is It Easy To Return An Item?
Yes, simply give us a call at 888.899.8776 or you can email our support team at support@audioadvice.com. Many times our team of experts can help figure out why the product might not be working like you expected and get things fixed over the phone, so don’t be surprised if we ask a few questions, we love troubleshooting!
If our tech help can not make you happy, we will email over a return shipping label with a Return Number.
Hopefully, you saved all of the original item’s box and packaging inserts. You will want to pack back up your return or exchange in the same way it came out of the original box. Once you have everything packaged correctly, tape the box on the top and bottom to assure it stays together. If Audio Advice shipped the item to you inside a second box, it's a good idea to use that same extra box to help prevent damage on its way back to us. To avoid it accidentally coming back to you, use a magic marker to cross out the old shipping label or just tear it off.
The return shipping label we send you will have our address on it, just make sure you take the box to the right shipper (UPS, FEDEX, or USPS) as per the label.
If you are close to one of our stores, please let us know if it is more convenient for you to return it to us directly. You will still need to get a return number by contacting us and shipping and/or restocking charges may apply.
When Will I See My Refund?
It usually takes around 7-14 days for the refund to show up on the payment method you used. We do inspect all returns for damage and accuracy of the item inside the box before issuing a refund. Some items may be subject to shipping and restocking fees.
Can I Exchange My Purchase For Something Different?
Sometimes those big speakers just don’t fit in the room or you might have bought a small subwoofer and later found out you’d love a bigger one. If you would like to make an exchange within 30 days of receiving your item, just give us a call at 888.899.8776 or email support@audioadvice.com and we will help work out the details. Additional shipping charges and return costs may apply.
How Do I Cancel An Order?
If the item has already shipped out or is a special order item, it is not possible to cancel the order. Please contact us at 888.899.8776 or email support@audioadvice.com to start the return process.
What If I Find Shipping Damage?
We need to know right away about any shipping damage. Please contact us at 888.899.8776 or email support@audioadvice.com within 48 hours of your delivery so we can get the ball rolling on making things right. It’s very helpful to take some pictures and email them to us if possible.
Can I Refuse A Shipment?
You can, but unless the item is damaged, shipping and restocking fees will be deducted from your refund. If your item arrives damaged and you are lucky enough to be there, snap some quick pics and refuse the order. Then contact us so we can get a replacement on the way.
What Happens If My Order Is Defective?
This is actually pretty rare, most consumer electronics work fine out of the box 99.9% of the time. We’d like for you to contact us first by calling 888.899.8776 or email support@audioadvice.com so we can help get to the bottom of things. If your item is indeed defective during the first 30 days, we can usually exchange it for a new, replacement unit.
What About Service After 30 Days?
Audio Advice has a great relationship with all of our brands and can help you with warranty service by the brand after our 30-day guarantee period. Even after the warranty expires, we can arrange for service by the brand on products purchased from Audio Advice. Just call 888.899.8776 or email support@audioadvice.com.
How Do You Determine A Restocking Fee?
You may not believe it, but sometimes we receive items back that were put in the box with zero packaging and are completely destroyed or are missing many of the pieces that came with the item. We also track serial numbers and will get back different serial numbers. We’ve even seen different items than what we shipped out be returned. However, it’s very important to package your return properly so that nothing goes missing or gets damaged in shipping, which will result in a restocking fee or even no refund at all. If a product is opened and the market value of the product is reduced, then a restocking fee may be applied to the cost of restocking and the reduced market value of the product. The bottom line is if you treat us fairly, we will do the same.
Audio Advice strives to provide industry-leading support and service while also maintaining the lowest prices available on products for our customers. We work hard with our vendors to bring our customers the best products at each price point. As a part of that process, we work with our vendors to provide the lowest pricing in our stores and on our website.
Our prices should always be the same as any other authorized dealer, including big-box retailers and major online retailers.
If you believe that you have found a lower advertised price from a legitimate authorized seller, call us and let us know so we can make sure we can correct any inadvertent error on our side. As a matter of policy, we update our prices automatically if a vendor changes its authorized pricing policies, so we generally have the best prices all the time. Increasingly, there are knock-off copies of products online, usually sold by non-authorized dealers.
Please be sure that the item meets the following conditions:
- The item is brand new, in stock, and available for purchase
- The item has the identical model number, color, etc as the item on our site.
- The seller is an authorized dealer
As always, our goal is to provide a terrific customer experience, including industry low prices. We appreciate your support.
