only if 5 subscriptions tho
When you have fewer than 5 subscriptions:
amazon.com > my account dropdown menu: my subscribe and save > under the delivery date they have "change the delivery date" > click a later date.
Keep moving the delivery date until you have 5 things in your subscription.
DO NOT "skip a delivery" or you lose the sale/ coupons that you ordered it with.
They send you an email with 2 or 3 days left to change the delivery. At that point, each item is in your 'orders' and you can review them to check that it's at a price you actually want to purchase it. If not - cancel an item, move delivery forward some more. etc.
There's also a thread with filler item to add to S&S to get to 5 items. I periodically get Glade air freshener for .89 - 1.09 as one of my items.
