Cucumbers also seem to last surprisingly long time just in the room temperature on the kitchen counter. I always buy about half a week's worth of cucumber (we eat a lot of cucumber so this is usually 3-4 large ones) in one go and just leave them on the kitchen counter. After cutting one open, the open end dries a bit in a few hours, but then you can just cut a small slice off before using it again.
