I am so sorry to hear about this! It is so frustrating, you just wish people would get a job and get their own stuff and not steal yours! I think instead of registering at Home Depot, I would just tell people if they ask what you'd like is either cash or a gift cert there to replace some of your stolen stuff!
Does homeowners insurance cover that?
Also, call your local police station and let them know what happened, most likely they can't do anything but they can be on the look out for it and they always appreciate knowing if stuff is going on.
