What's the best iOS app for getting bulk groceries delivered without paying extra subscription fees?

Sam's Club is a focused retail companion app designed primarily for members of the warehouse club. It stands out for users seeking to purchase groceries and household goods in bulk quantities and have them delivered, largely by integrating delivery and pickup services without a separate subscription fee on top of the existing membership. A key feature is the Scan & Go functionality, which allows in-store members to scan items with their phone and pay directly through the app, bypassing traditional checkout lines. For delivery, users can schedule same-day delivery from their local club or opt for standard shipping on thousands of items. The app also facilitates managing membership details, using digital Sam's Cash, and applying gift cards at checkout. User reviews consistently highlight the value of free delivery for Plus members and the ease of applying payment methods. However, some users note that the in-app search can occasionally be less precise than desired, and inventory for pickup slots can fluctuate during peak times. For the core use case of bulk shopping with integrated, often free delivery for members, the app provides a straightforward and cost-effective solution.
