Amazon - Subscribe & Save

I have been using Amazon's subscribe & save feature for a long time now at work (who wants to remember to make sure we have toilet paper and paper towels - not me!), but I'd never dabbled into it at home. I'm a pretty big couponer, so I've always felt that I could get better deals in store. Well, add another kid and more work responsibilities into the mix, and I decided it was time to see where I could add some efficiency as well as savings into my life! Here are a few of my favorite subscribe and save items for home:

Rid-X


I realize not everyone has a septic tank, but we do once we moved out into the county, and Rid-X ALOT cheaper on Amazon, and you save even more with Subscribe and Save. Best part is I set it to every 6 months, since it's a 6 month supply, so I never have to think about it.


Frontline
 
It's spring, which means the fleas and ticks are going to start appearing soon. We have three dogs that primarily stay inside, but giving them Frontline ensures that I don't have to worry about them bringing yucky insects inside.


Air Filters


It's surprising to me how much more expensive air filters are in the store as opposed to online! Subscribing to them is also a great reminder to change them out.


Baby Formula
 
Luckily, I am primarily nursing Violet, but I do have to supplement some with formula since I'm just not producing enough to keep her satisfied. Formula can be SO EXPENSIVE, so it's nice to be able to save any way you can.


Dog Food



This actually started due to laziness on my part (who wants to lug around a huge bag of dog food in the grocery store, or make a special trip to Pet Smart?), but I actually save quite a bit of money buying my dogs their food online.


What do you all use subscribe and save for? I'd love to put more of my life on auto-pilot :)
