Promotional offers are delivered to consumers when they are in close proximity to the point-of-sale. By delivering electronic coupons to consumers' mobile devices, consumers are more likely to take advantage of the special offers. Discount coupons and other special incentive offers are delivered to and stored on cellphones and other PDA's. These digital coupons can also include bar codes that can be scanned by bar code readers, directly from the cellphone screen.
