Amazon’s been taking aim at grocery stores recently, and its most recent program, ‘Prime Pantry,’ could be its biggest hit yet. Prime Pantry lets Amazon Prime customers in the contiguous 48 United States ship 45 pounds’ worth of household goods for a flat fee of $6. And they’re not selling Costco-like bulk quantities, either – Amazon is selling items in “everyday sizes,” just like you’d buy at the grocery store. Prime Pantry lets you buy a wide range of goods, like soda and water, paper and laundry products, breakfast cereal, personal care products and more. As you add things to your “box,” Amazon will tell you exactly how much room is left. You can load whatever you want in the box, but customers looking to buy heavy or bulky items that don’t usually ship for free should find the program especially appealing. If you want to learn more about the program – or if you’re running low on Cheerios and want to stock up – you can check out the program now at Amazon.com/PrimePantry.
