What surprises me the most is my dh understands when I buy more yarn!!!
When the first lys that I worked in was closing they reduced their remaining stock to 75% off. This was Jan first and people that had bought yarn before had the right to return it. Well little of the returned stock made it to the stock floor. It usually went into the box of one of the employes, me included.
I have helped several stores dispose of their inventory!! This was before the re-surgance of knitting.
