Abstract: Methods and systems are disclosed in which a guaranteed delivery advertisement may be appended with a non-guaranteed delivery advertisement. The guaranteed delivery advertisement may be, for example, a manufacturer or brand advertisement, and the non-guaranteed delivery advertisement may be, for example, a retailer advertisement. The guaranteed delivery advertisement may relate to a particular brand and/or product and the non-guaranteed delivery advertisement may relate to a purchasing opportunity for that particular brand and/or product. The guaranteed delivery advertisement may be selected based on targeting information and the non-guaranteed delivery advertisement may be selected based on factors such as, for example, the manufacturer name, the product name, the product type, a related product, price, availability of the product, discount, location of the retailer, etc.
