Suffer. I just suffer without, neccessity is the mother of invention and all that. Course there are a few things I wont go without, but generally not buying something for a week or more doesn't cause much problem here.
I also make a list if I can, a running list costs me more money cause I remember more stuff

, but I do it when I am really annoyed at forgettting for a few weeks in a row. (we only shop on Thursdays, cept for gifts sometimes on sundays - DHs days off)
