I recently retired a topeak trunk bag/pannier (worn out due to age), though I'm not throwing it out. In it's place I got a Carradice Nelson Longflap for my commutes.

I also have a small seat bag for tools, but rarely ever use it.

Oh, and then there's the Ortlieb panniers, front and back for touring.

And a back pack.

And a couple of dry stuff sacks to put clothes in before they go in one of the above.

I'm glad you didn't ask how many racks I have.
