1. zZounds offers the industry‘s most musician-friendly payment plans

zZounds offers a variety of Play as You Pay installment plans that allow you to get the gear you want today. While our competitors might offer house credit cards that require you to fill out an application and pass a credit check, our payment plans are easy to get, simple to use, and, best of all, accrue zero interest. Unlike those house credit cards that can leave you vulnerable to exorbitant interest charges once the promotional period ends, we never have and never will charge interest when you take advantage of one of the zZounds Play as You Pay plans.
