I'm feeling a bit ripped off right now.
I bought an exterior receptacle box for a GFCI. The box comes with 5 threaded holes, 2 on each end and 1 in the back. However, it only comes with 2 plugs. Now, I could be wrong, and I know there are many cases where only 2 plugs are required, but I'm guessing the majority need more. Any installation at the end of a run for a light or a receptacle is only going to use 1 hole and most installations in the middle of a run will only use 2 holes.
So, if my guess is correct, then the majority of consumers have to spend another couple of bucks ($2.45 to be exact) to buy a pack of plugs for the extra holes. Of course, the plugs come in packs of 4, so unless you're installing more than one box, odds are you'll have extras when you're done.
