The ten cent bundt pan has been put to good use this year. Buy it cheap to find out if it is something you'll use. This pan is a "yes".
One other "yes" is my pair of Dansko shoes. I thought I wanted a pair for a couple years. When I found a nearly new pair at a rummage sale last summer for $2 I gave them a try. After wearing them nearly every day at work they are also a "yes". Worth paying full price for an additional pair if/when these wear out.
I'm getting rid of about 12 pairs of work shoes that I rotated before these Dansko shoes.
