We have Amazon Prime, and I use S&S every month (our shipment just came in yesterday, actually!)
In yesterday’s shipment, we had some toiletries, Pull-Ups, vitamins, granola bars, and kids’ Ibuprofen. Next month, according to the schedule, are more vitamins, taco seasoning, and a few toiletries. I’m sure it will change as the month goes on.
Pros:
-ships for free
-when you look for the sales, you can find excellent deals
-you can change or delete items from your Subscribe and Save any time (up to three days before shipment). Even if you have only ordered an item once, you can delete it from your S&S.
Cons:
-without shopping the sales, items tend to be more expensive than you would find at a bulk retailer
-if you don’t have five items in your S&S, the discount is only 5%, compared to 15%.
-your shipment comes only once a month, so if you run out of something before then, you’ll either have to wait until the next shipment or pay full price by ordering immediately.
I fine-tune my purchase each month to make sure I am getting what we need when we need it, and that the price of the item is reasonable. I do use it a lot for toilet paper, shampoo, body wash, diapers/Pull-Ups, and on-the-go snacks. I do shop the sales, though, and delete a subscription if the price goes back up after my first shipment.
Hope that helps!
