There’s something comforting in knowing that 144 rolls of toilet paper will show up at my front door before I need them. And that opening the four cases of San Pellegrino sparkling fruit beverages that follow will make me happy like nothing else can. Well, nothing except that I will never again run to a drugstore for feminine hygiene products because they, too, show up regularly.

At my house, we have given up buying large things at stores because I’m tired of carrying them up stairs. So I just pre-order my household supplies on Amazon.com and let FedEx carry them up the stairs.

I subscribe online (on the Subscribe and Save menu) and schedule monthly, bimonthly or quarterly deliveries. For instance, paper towels and laundry detergent arrive every other month. Basmati rice arrives quarterly. And like the toilet paper that also arrives every three months, we maintain a perpetual supply of dishwasher soap, orzo and chia seeds.

I probably pay a few more dollars than at a store, but I save a lot of money on the cost of blood pressure medicine, wear and tear on my artificial knees, and gas.

The only down side I’ve found is that sometimes we have too much of a good thing and find ourselves over-stocked, perhaps with two gross of toilet paper rolls, or 40 pounds of rice. In that case, I simply suspend delivery online until we use what we have stashed in closets, cabinets and under beds.

And honestly, the only way Amazon could have made my life any easier is if it had also delivered my children.
