These discounts apply to orders of any books, and can be redeemed by ordering multiple copies of the same book, or through a number of different titles. The discounts are automatically applied in your cart, which means that obtaining bulk-buy discounts is a simple process.
If you wish to purchase more than ten books, Packt can offer you a larger discount. Simply email BulkSales@PacktPub.com, and your email will go straight through to somebody who can help you further with this.
