I am selling items to organize things due to moving. Most items are used, and I am selling things I think are too good to throw away. I will pack them simply and ship them using the cheapest shipping method. Also, I may open and repackage new items to sell them at a lower price. Please understand that there may be oversights as I am a non-professional inspector. I appreciate your understanding and cooperation.
