UpscaleRiver today released Buy or Trash 1.0 for iPhone and iPod touch users. The application is a shopping decision engine powered by a community of fellow shoppers. Users help each other decide on purchases by voting whether or not the products are a good buy. Features such as Facebook and Twitter integration, push notifications and website syncing make the app easy to use and immensely helpful to shoppers, especially when facing impulse purchases.
