It's nice to not aggregate your items. I looked at my prime history, and it's a combination of books, music, and household items that don't always meet the $35 free shipping (used to be $25 until Q4 last year). For example, my most recent purchase was a $15 book that I got on 2 day shipping.

Also the way free supersaver shipping works is that you wait 3 days or until the warehouse is low on work, whichever comes first, before they pick your order. You then have to wait for 3-5 day ground shipping. You can pay for shipping at any speed to avoid the product picking delay.
