How Amazon's Subscribe & Save Can Save You Major Cash

As if we needed another reason to hit up Amazon.com--Prime, Pantry, and Dash Buttons, anyone?--they've gone and rolled out another feature to get hooked on. The Subscribe & Save function is the mega marketplace's solution to a digital grocery list, except instead of writing down (or remembering) everything you need to buy before your next trip to the store, you sign up for items you know you'll need - and use regularly - ahead of time, like toilet paper or coffee pods, for instance.
