Google Express allows both Android and iOS users to shop online from a large number of stores, and have that purchase shipped to them. First-time users get to take 20% (up to $20) off their bill using the checkout code MAYSAVE19. There have been some changes recently to Google Express. In January, Walmart mysteriously disappeared leaving Target as the largest store in the app. If you have a Google Account, your payment and shipping information is already available. This allows you to compare prices at multiple stores and checkout quickly when you’re ready to make a purchase. Express already works with Google Assistant and allows users to shop by using their voices.
