Discount codes are a special type of voucher system that is used for Internet shopping. They function much like traditional vouchers, although there are some major difference in terms of implementation. Unlike a traditional paper voucher that is given out through direct mail and print advertising campaigns, online vouchers are actually codes and have no physicality.
However, just like traditional vouchers, online discount codes are used by customers as a way to save money on goods and services. They are input into an e-commerce checkout system at the time of purchase, allowing for a discount on a particular product, an entire bill, or any associated shipping costs. Coupons are often listed on dedicated coupons websites, where Banana Republic Coupons may be listed alongside those from hundreds of other retailers.

Banana Republic is a popular brand of clothing, as well as a chain of clothing stores owned by Gap Inc. They have 610 retail stores around the world, and a large Internet sector that sells many of their products online. The original Banana Republic was founded in 1978 by Mel and Patricia Ziegler. It had two stores in its original incarnation, and sold mostly safari and travel related clothing. They became well known for their eccentric hand illustrated designs, although they expanded into other areas as their popularity grew. Banana Republic engage in a number of promotional campaigns, including print advertising, billboards, Internet advertising, and discount codes.

Discount codes are used as a way to encourage brand loyalty, expand the customer base, and track advertising campaigns. While many people do not think about the marketing potential of discount codes, they are a great way for businesses to analyse their advertising campaigns. Because different codes can be linked to different ads, businesses can easily track the response rates associated with particular commercials. Consumers may receive promotional codes in emails from companies or find them through coupon websites operated by third party affiliate businesses.
