Target

General Mills activated its "Box Tops for Education" cause platform to promise Target shoppers 25 "Bonus Box Tops" with the purchase of four qualifying Annie’s SKUs. 

Target recently updated its mobile application to let shoppers indicate where in their cars they want their orders placed when using the retailer's curbside pickup service, Drive Up.

While its potential as a selling tool is still to be determined, retailers have been moving to establish their presence on the social media platform.
