About 5 months ago I noticed while buying something via Amazon, that I could get an even better price if I agreed to “subscribe” to buying it routinely.  For example, as I was buying laundry detergent I could subscribe to automatically buy a quantity either each month or every 6 months.  With that deal, I got free shipping and a 15% discount on the already best price I could find.  Now, all I have to do is figure out what else I want to subscribe for.  Vitamins are on the list.  I wish they could deliver more types of groceries!!!
