Visit an auction site like eBay. Suppliers often use auction sites

Order strings from an online wholesaler, such as www.musiciansfriend.com, www.juststrings.com or www.stringthis.com. These outlets often offer discounts for bulk purchases and allow you to choose the quantity you want to buy.

Call the manufacturer of your favorite strings or visit the company’s website. Many manufacturers sell strings in bulk and are delivered worldwide.
