Final answer:
The discount for using a DB mug varies by company and could be a percentage off, a fixed discount, or other benefits. To find out the exact discount, one should check the company's policies or ask customer service.
Step-by-step explanation:
The discount a customer receives for using a DB mug is typically issued by the company as a part of their promotional or environmental sustainability efforts. However, without explicit information regarding the particular company's discount policy, it's impossible to provide a direct answer. Generally, companies might offer a percentage off the purchase price, a fixed amount discount, or an additional benefit like a free refill or extra loyalty points. Discounts vary by company and could change over time.
To determine the exact discount for using a DB mug, one would have to refer to the company's official policies or promotions. Customers can often find this information at the point of purchase, on the company's official website, or by inquiring directly with customer service. These sustainability efforts encourage the use of reusable items to minimize waste and may be part of a wider environmental campaign. Always check with the specific company for their current offers.
