Absolutely; same here. I try to group my shipments even though shipping cost is no longer an issue with Prime. In reality they probably have a deal worked out so that 2-day shipping doesn't cost practically anything, but I still feel that guilt when the expedite that $3.35 item to me. I wonder if guilt's part of the Prime business strategy? I still haven't figured out how it works out in their favor (which it has to, or they wouldn't offer it)
