Shipping containers can be purchased in new or used condition. You can expect the pricing of used shipping containers to vary based on age, condition, delivery fees, and so on. According to Container Discounts, a new 40-foot shipping container can cost about $4,500 and a used 40-foot container can cost about $2,200. These are ballpark figures but should provide a rough idea of cost. Shipping containers are designed to be durable and can last for decades. Since it's likely that you'll be doing interior and exterior modifications, a used shipping container may be more than suitable.
