With retailers moving out of crisis mode, they're back to investing in new bells and whistles for their stores and websites. Such as: Apps that send coupons to your smartphone or digicams that let you post pictures of a dress you're considering to your Facebook page.
Shopkick's smartphone app combines location-based features with shopping. The hot startup's plan: When you walk into any partnering retailer, the app will alert you to deals at that store, and reward you with "Kickbucks" just for being there.
