Systems, devices, and methods used to provide real-time product information for retail products and services are generally disclosed herein. One example embodiment includes a referral application operating on a smartphone, configured to correlate data from multiple sources and provide context-aware recommendations and information relevant to a product or service being evaluated by a consumer in the physical shopping environment (such as a retail store). For example, the data may be obtained from a retailer's product information database, a retailer's competitor information database, an advertiser information database, an Internet-hosted service, a social network, or similar internal or external information sources. The real-time product information may be correlated, aggregated, and displayed to the user to either facilitate the retail purchase in the store, or encourage another online or retail purchase. Techniques for providing location-based advertisements and tailored product offerings based on the user's shopping activity are also described herein.
