Essential Retail's Innovation Blog is starting to provide the 'voice of the shopper' articles to accompany the main breaking B2B news, features and big interviews that appear on the pages of essentialretail.com.

The publication writes so much about the new technology filtering into the industry, that it seems prudent to understand how easy and successful these new systems and gadgets are to use from a customer perspective.

For this week's Retail Ramble podcast, Ben Sillitoe, editor of Essential Retail, and Caroline Baldwin, deputy editor, trialled the new Sainsbury's Chop Chop mobile app and Waitrose's Quick Check scan as you shop app. Tune in to hear about their experiences.
