I mentioned that I order a lot of household goods and toiletries from Amazon. I use the subscribe and save feature. Basically, the way it works is you subscribe to have items automatically delivered to you at a discounted rate. It is perfect for things like diapers, wipes, detergent, toothpaste, deodorant, etc. You can set the frequency you would like to have items delivered, and if you need something sooner than your mail out date, you can bump up the order by clicking need more right away feature.
I'm always tweaking my subscribe and save account to suit our needs, adding items and canceling subscriptions. Sometimes Amazon quits offering an item you subscribe to. The system is always a work in progress.
But it sure beats running to the drug store at 9pm for toilet paper. I love the convenience of having diapers sent every month. I don't have to think "oh, we need diapers." I love not thinking.
I'm all about less decision making and fewer errands. It helps me so much to put a few things on autopilot in my life.
Is it cheaper?
Yes, I think it is. Granted, I don't buy everything using the subscribe and save method. Recently, I cancelled toilet paper because Costco has the better deal.
Anyway, hope that answers any questions out there!
