Model Dell: The Art of the Affiliate Coupon
Along with having an innovative supply chain, there's another reason Dell is the largest computer company in the world. They always offer great coupon codes to online affiliates that let the buyer "in" on deals that they otherwise wouldn't get.
By offering coupon and discount codes that are both new promotions and/or expiring deals, it motivates buyers into taking advantage of a one time offer. It's also a great way to push inventory and make room for new products.
Have you noticed Dell is now promoting digital cameras, flash memory, and more electronic products from other retailers? Their success in the e-commerce space comes with the help of affiliates, and now they are promoting a wide range of electronics with similar coupon codes to what was once only available to computer discounts. Promotions like these benefit the buyer AND seller.
There's a reason "dell coupon" was searched twice as much as "online coupon" in April (from Yahoo search statistics). It's because not enough affiliates are pushing their products with coupon codes. Retailers should model the Dell affiliate coupons offers; their success comes from many angles.
