Price Comparison Systems and Methods

A computer system comprising one or more processors and one or more memory devices operably coupled to the one or more memory devices, the one or more memory devices storing executable and operational code effective to cause the one or more processors to:

• receive a record of a first online transaction with a first entity;
• subsequent to the first transaction, identify for each item identifier of at least a portion of the one or more item identifiers, a third party record, the third party record corresponding to the each item identifier and having a third party price;
• subsequent to the first transaction, identify one or more discounted identifiers of the one or more item identifiers, the third party price of the third party record corresponding to the discounted identifiers being less than the price paid for the one or more discounted identifiers by one or more price differences;
• credit an account associated with the user identifier with an amount corresponding to the one or more price differences;
• and
• apply the amount toward a purchase price of a second transaction subsequent to the first transaction.

A method comprising:

• receiving, by a server system, a record of a first transaction concluded on a point of sale (POS), the record including one or more item identifiers, and a price paid for each item identifier of the one or more item identifiers;
• subsequent to the first transaction, identifying, by the server system, for each item identifier of at least a portion of the one or more item identifiers, a third party record, the third party record corresponding to the each item identifier and having a third party price;
• subsequent to the first transaction, identifying, by the server system, one or more discounted identifiers of the one or more item identifiers, the third party price of the third party record corresponding to the discounted identifiers being less than the price paid for the one or more discounted identifiers by one or more price differences;
• crediting, by the server system, the user with an amount corresponding to the one or more price differences;
• and
• applying, by the server system, the amount toward a purchase price of a second transaction subsequent to the first transaction, second transaction being an online transaction;
• determining, by the server system, based exclusively on the applying of the amount toward the purchase price of the second transaction, that the first and second transactions are associated with the same user;
• characterizing, by the server system, interests of the user based on the first and second transactions;
• and
• generating, by the server system, at least one of a recommendation and a promotion for a product corresponding to the characterizing of the interests of the user.
