I've had Amazon combine separate orders into a single box.

If your orders are really 30 and 10 minutes apart, Amazon will ship them together if it can.

That's weird, I don't think I've ever seen that happen. I'm constantly having multiple doors pop open at the locker.

Although maybe it's possible they do it some of the time and I'm actually much worse about fragmenting my orders than I think :)
