Customer Kudos
"Just wanted to say you guys totally deserve your Top 3 Newsweek ranking. You guys make it possible for those who can't drop a few grand in cash all at once to get their dream instrument and begin learning and creating. But even better, you don't harass people about their current balance as long as the payment plan is followed. The ability to make changes to the pay schedule is a life saver at times. From my perspective and experience spending thousands with zZounds, you guys seem like laid back good people. Congrats on the rating."
