Target is taking on Amazon's Prime Pantry with its own version called "Restock." The company announced a trial run of its new service today, which it tested with employees earlier this year. Like Prime Pantry, with Restock, customers can fill a box with up to 45 pounds of loot for a flat added fee. But Target is undercutting Amazon by a dollar, pricing their box at just $5. Additionally, Target is offering next-day service with their boxes, whereas Amazon's usually arrive within four business days.
