The difference between the bill of lading and shopping card both in the scope of use. The bill of lading is mainly used to redeem a fixed number of goods, and the bill of lading will also be a special surface of the type of goods that can be withdrawn from each coupon. The use of shopping cards is more extensive, shopping cards are generally restricted to the use of the place, but the goods can be purchased is not fixed. For example, the Starbucks mooncake coupon is a bill of lading, which can only be used to redeem a certain mooncake gift box at Starbucks. But a Starbucks shopping card is only restricted to use in Starbucks, but there is no restriction on what you can buy with it.

Shopping cards are more flexible in their use, and can be used to purchase different types of goods and support multiple purchases, making them more popular than bills of lading.
