1. We offer the most flexible payment plans in the biz

zZounds offers a number of different installment payment plans that make it affordable and convenient for you to get the gear you really want today, without racking up risky credit card debt.

Other stores offer house credit cards that require you to fill out an application and pass a credit check--and, if you qualify, leave you vulnerable to exorbitant interest charges once the initial promotional period ends. zZounds payment plans are easy to get and simple to use; plus we'll never charge you interest!

2. We guarantee the lowest price

If we don't already have the lowest price, just send us a link to any legitimate competitor's offer, and we'll beat their price as long as we're not losing money on the deal.

To submit a request for a lower price, click "Seen it for less?" on any product page. We answer most lowest price requests within two hours. For extra peace of mind, you also have 30 days after your purchase to find a lower price; if you do, we'll refund the difference.

3. You'll get your gear fast

Because we have two well-situated warehouses--one on each coast--nearly three- quarters of the US population is located within our two-day shipping zones. Plus, we keep both warehouses well stocked with all the most popular products, so you'll usually get your gear fast without having to pay more for expedited shipping.

In fact, zZounds offers free two-day delivery on many of our best-selling products!

4. We make returns super easy

You have 30 days to try your gear at home, in your practice space or studio. If you're not absolutely in love with the sound you're getting, just let us know. We'll promptly arrange for an exchange or a refund without the hassles or hidden charges you face with some of our competitors. If there's something wrong with the gear you bought from us, we'll email you an electronic return label so you can return it easily and free of charge.

5. Our customer service is consistently rated the best

zZounds customer service is consistently rated at or near the top on every major comparison shopping website--probably because we only hire experienced musicians with outstanding customer service skills to work in our call center, and they don't work on commission. To us, this is our most meaningful measure of success. zZounds has served over a million customers since 1996, and they're the only critics whose reviews really matter to us.
