Well, that title pretty much tells you all I know.  The savings are "up to" 70% off and the sale is for Monday only. 

By the way, I finally did the math and decided to give the Amazon grocery subscription service a try.  I have to use a specific brand of diapers due to my little's sensitive skin so I can't save $ getting the store brand.  Anyway, the Amazon cost for the brand I purchase is the same as it is at the store, plus when I subscribed I received a discount on that price and free shipping. 

SO, now I am getting my diapers delivered to my house for less than it cost me to buy them locally.  I'm also getting some vitamins for the kids delivered at regular intervals (with the same discount). 

BUT, I don't recommend getting liquid detergent delivered.  The price and convenience were great- who likes lugging detergent around?  But, one of the bottles in the box fell over in transit and leaked all over the others. Yuck!
