Purchasing, redemption and settlement systems and methods are provided wherein a buyer takes possession of a product at a retailer. A purchasing system may communicate with a buyer through a communication network to establish a first price for a product between the buyer and a seller. The purchasing system may also arrange for the buyer to take possession of the product at a retailer, different from the seller, that offers the product for sale at a second price. Verification information, which enables the retailer to authorize the buyer to take possession of the product, is transmitted to the retailer. The buyer provides a payment, based on the first price, to the purchasing system in exchange for the right to take possession of the product at the retailer. In one embodiment, the purchasing system receives a buyer offer, including an offer price, related to the product. In another embodiment, the purchasing system transmits redemption information, including a redemption code, to the buyer. The redemption information may also include information that enables the creation of a voucher to be used when taking possession of the product. The purchasing system may also receive information related to an attempt by the buyer to take possession of the product, including the redemption code, from the retailer.
