reason not to go to REI

So I go buy a nice hiking pack from REI and get it home only to find dirty underwear in it! At least they took it back and upgraded me to a bigger one. Even with the bigger one I can't fit all my stuff in it! I leave tomorrow! And I now have a power of attorney signed and notorized so Cory can't yell at me! Back to packing. Do you think I should bring a roll of toilet paper?
