I don't know why I never thought of this before. We have Amazon Prime which I love. We get free two day shipping on anything we order and some other perks. Recently it dawned on me, why don't I shop household products on there?? It saves me a trip and it might save me some money on bulkier items like diapers.
Now that it's summer and I have a little more time on my hands, I created a "wish list" on there with commonly used household products: diapers, dish washer detergent, you get the idea. Most of it was a little cheap and larger quantity. You can also "subscribe" to certain products (mostly baby items) on a 2, 3, 4, 6 months and save even more.
