I am a big fan of an Amazon service that saves me both time and money - Amazon Subscribe and Save. It is an automated ordering service for supplies you use all the time. Things that you regularly use like paper towels, cleaning products and batteries are all available on the site. You can get things like sports drinks, chips, crackers and other grocery items as well.
By setting up a recurring order based on how quickly you go through inventory, you can control when items are delivered, save time manually ordering and save space by having it delivered when you need it. You save up to 15% on your entire order when you receive 5 or more subscriptions on your monthly delivery day and there is free shipping on every Subscribe & Save shipment. You can change or cancel at any time and you only pay when the item is shipped. Pretty cool way to help run your business. Click the logo above or this link for more info.
